Turkey Run: A Challenging-Moderate 4 or 6.3 Mile Hike with Rock Scrambles
Turkey Run: A Challenging-Moderate 4 or 6.3 Mile Hike with Rock Scrambles
**Turkey Run: A Challenging-Moderate 4 or 6.3 Mile Hike with Rock Scrambles** SEE IMPORTANT INFORMATION ON REGISTRATION UNDER "NOTES." This is a great hike to step up your hiking to a more challenging level due to the terrain. There are two loops in this hike: one for 4 miles and a second for 2.3 miles. Work on building your hiking strength while challenging yourself to a rock scramble. This hike would be rated a moderate hike other than the rock scramble over a stream and other stream crossings using ropes, which earns it a “challenging moderate”. Please be aware, that the stream crossings and scrambles are challenging, and that good footwear is a must. Turkey Run Park has a number of wooded and riverside trails. Turkey Run Park preserves a vertical slice of the Potomac Gorge ecosystem. A unique combination of flora and fauna makes a home in the park's riverbanks, flood terraces, upland forest, streams, and underground seeps. There is also a variety of fauna that lives along and in the river. You may see cormorants and a variety of water birds. Trails in Turkey Run Park cross through several of the distinct habitats that make up the Potomac Gorge ecosystem. The Potomac Heritage Trail (http://www.nps.gov/pohe/planyourvisit/index.htm) also runs through the park. Along our route is a fun rock scramble and six stream crossings that you cross using rocks, and of course, a helping hand is always offered. The extra 2.3 miles is challenging in its own way. While we hike mostly along the river and its beautiful views, we will need to navigate several downed trees including one that is quite a challenge. The 4 mile hike should end around noon and the second around 1:30 PM. A leashed, well-trained Fido is allowed on this hike. Bring a lunch to enjoy between the two hikes. **Time to Meet**: Please meet at 9:45 for introductions and sign in. We will start hiking promptly at 10:00 **Contact Information**: Please use the comments feature for routine comments and questions. The hike Leaders are Christa (410-610-6254) and Tim (202-744-0289). Call or text as needed. **Directions to Trailhead**: It is best to use the GPS coordinates. They will take you directly to the parking lot. The GPS Coordinates are [38.964346, -77.153034](https://www.google.com/search?q=38.964346%2C+-77.153034&rlz=1C1ONGR_enUS1207US1207&oq=38.964346%2C+-77.153034&gs_lcrp=EgZjaHJvbWUyBggAEEUYOdIBCTM0NTRqMGoxNagCCLACAfEF4ILw8-9EEOc&sourceid=chrome&ie=UTF-8) Turkey Run Park in Virginia is located along the George Washington Memorial Parkway in McLean, VA 22101. It is accessed via the GW Parkway (Exit 43). We will meet in the main parking, C-1 lot near the parkway exit when coming from the North; when coming from the South the exit is almost immediately. **Rating**: Challenging-Moderate **Distance**: 6 miles total (Loop 1: 4 miles and Loop 2: 2.3 miles) **Elevation Gain**: Approximately 500 feet **Pace**: 2.0 to 2.5 miles per hour **Facilities**: There are no restrooms near the trailhead. **Fees**: no fees **Cancellation**: In the unlikely event that the hike needs to be cancelled, it may be cancelled up to the evening before the hike.

Abura Soba and Uji Matcha at Kajiken and Kyo Matcha in Annandale!
Abura Soba and Uji Matcha at Kajiken and Kyo Matcha in Annandale!
Join us for the soooo good Abura Soba at ***Kajiken*** in Annandale! ***What is Abura Soba?*** Abura Soba is a soupless noodle, mixed with house special sauces - chili oil, souy sauce, vinegar, minced garlic and pepper powder. It is the ultimate noodle where you can fully enjoy the taste. Kajiken is the pioneer of Nagoya-style Abura Soba, serving bold, brothless noodles since 2010. Baltimore Magazine: If you’ve never been to a ramen shop, Kajiken would be an excellent place to start. And if your idea of fun is a big bowl of noodles drenched in porky goodness, you have someplace to be. A long counter bar fronts the stoves, helmed by cooks tending vats of boiling water. Low weather systems move above the pots, into which the noodles are dropped and lifted with impressive dexterity. The entire crew will call out as you enter and exit—cries of “Irasshaimase” (welcome) and “Arigato gozaimasu” (thank you very much) like cheerful incantations. And then there are the bowls of noodles, in this case an iteration of ramen called abura soba or mazesoba, which is not soba at all but the thicker version of ramen noodles, served with a variety of accompaniments and without broth. Kajiken (Baltimore) is the first U.S. location of a popular Japanese abura soba chain that began in Nagoya and which now numbers some 100 locations worldwide. Ramen and its variations have been essential for a long time in Japan; tsukemen, or dip ramen, became popular about 10 years ago in American cities, and abura soba has also made the jump, especially to college towns. Kajiken specializes in various toppings for noodles, so you can experiment with things like mentaiko (fish roe), umeboshi (Japanese plum), and menma (bamboo shoots), or add what you especially like (tomatoes, cheddar, soft-boiled eggs) to make an idiosyncratic mash-up. This can be a lot, especially as the restaurant doesn’t allow substitutions, and the abura soba versions—a basic, with chashu (discs of roast pork), menma, scallions, and nori; curry; carbonara; beef and onions; a cold version; and a vegan iteration—already come with plenty of ingredients. You will be instructed to stir everything up with your chopsticks, as the absence of soup means that the tare, which is the concentrated sauce, has been installed at the bottom of your bowl. Be sure to dose your bowl with rice vinegar and chile oil, which give some extra flavor and, more importantly, a hit of acid to counter all the pork, pasta, and oil. There are other items on the menu, notably more traditional tonkotsu ramen, made Hakata-style, as well as donburi rice bowls, and an impressive list of appetizers. Kajiken has very good versions of gyoza, or pork dumplings; and karaage, or fried chicken. And best of all, there is takoyaki, fried balls of dough embedded with octopus and topped with shaved bonito, curls of dried fish that wave in the heat and make the dish look disconcertingly like a terrarium. (Don’t be deterred—it’s delicious.) There’s no booze or hot tea, but there is salted plum soda, a sour-salty-sweet drink that’s worth trying. There is also a very cute little desert shop attached (Kyo Matcha) that has a surprisingly robust dessert menu, including ice cream, yuzu cheesecake, and wondrous slices of deep green matcha crepe cake. Check out Kajiken menu [here ](https://www.kajiken-usa.com/) Check out Kyo Matcha menu [here](https://www.kyotomatcha.us/menu) **WAITLIST:** Meetup does not allow a waitlist for paid events. If this event fills and you are interested in adding your name to the waitlist, please send host a message through the app. To enhance the opportunity for great conversation, we would like to keep the group small. Please feel free to sign-up to meet us along with up to 2 friends. In the future, we will vary the days of the week, geography and the cost of restaurants so that we can attract many different types of diners. PLEASE MAKE SURE YOU ARE COMMITTED TO GO WHEN YOU RSVP FOR THIS EVENT. In the event our group incurs a fee for no-shows / late cancellations, your ability to RSVP for future events will be restricted. Thank you in advance for your understanding.Feel free to make suggestions for future meet locations. All diners will have their own tab to avoid any confusion. \*\* The small non-refundable registration fee helps us share the cost associated with Meetup platform ($360/year) and reduces the likelihood of no-shows, allowing us to better plan our events and accommodate attendees. Thank you in advance for your understanding!\*\* If you are unable to join us in April, we hope you'll stay interested and join us for a meal in the future. Looking forward to seeing you at Kajiken in Annandale!

PFS 6-07 A God Falls Where Magic Fails [7-10]
PFS 6-07 A God Falls Where Magic Fails [7-10]
When Gorum died, shards of his divine being rained down. One of these warshards landed in an ooze being transported outside of Oenopion. The newly-empowered creature escaped its confines and headed south towards the Mana Wastes. The Nexian forces haven't be able to deal with it, and have turned to hiring mercenaries. The Pathfinder Society learns of this chance to get their hands on another warshard, and has an arclord ally get them on the short list of candidates. The PCs must prove their mettle over the other candidates before tracking this newly divine war ooze along the borders to the waste. What's more, the Mana Wastes themselves aren't going to make this mission any easier, and no one yet understands the full impact that warshards might have on creatures, so there's no telling the capabilities of this warooze.

April 19 Invasive Plant Removal at TRI
April 19 Invasive Plant Removal at TRI
It's April and it's time to get outside! We are NPS Weed Warriors and Arlington Regional Master Naturalists and you should volunteer with us on Sunday, April 19 to learn about nature and remove invasive plants from everyone's favorite urban island. Meet us at the entrance to the bridge (on the parking lot side, look for the sign) at 10:00 and bring your garden gloves and loppers/pruners if you have them. If not, we can provide gloves and tools. Wear long sleeves and pants and don't forget a water bottle. We will have tasks ranging from easy (cutting English ivy and honeysuckle vines from trees) to hard (sawing down bush honeysuckle). Parking at TRI can be tight if it's a pretty day. When the parking lot is full, you can park in Rosslyn and take the trail down. If you can bike or walk or take public transit, that's wonderful. We'll see you there! Erica, Stephanie, and Heidi P.S. If you can't wait until then to RIP (Remove Invasive Plants!), go here to find more volunteer opportunities in Arlington parks: [Volunteer to Restore Native Habitat – Arlington Regional Master Naturalists (armn.org)](https://armn.org/volunteer-opportunities/)

From Shared Logic to Shared Pixels: A KMP & CMP Deep Dive && Swift on Android
DC iOS returns to the Capital One campus for another meetup! And not only just DC iOS, we are collaborating with [iOSoHo](https://www.meetup.com/iosoho/), [DC Android](https://www.meetup.com/dcandroid/), [New York Android](https://www.meetup.com/new-york-android-engineers/) and the Dallas iOS Developers Group for a big combined meetup! Come and meet with fellow Apple AND Android developers in the DC Area, enjoy some food, networking, and a great tech talk! PLEASE INDICATE IF YOU WILL BE ATTENDING IN PERSON OR OVER ZOOM. **Agenda (NOTE THE LATER START TIME):** • 6:00 PM - Doors Open (in-person attendees). **Don't forget your ID!** • 6:30 PM - Welcome (in-person and Zoom attendees) • 6:35 PM - **First Talk: From Shared Logic to Shared Pixels: A KMP & CMP Deep Dive** (Live from DC) • 7:05 PM - Community Announcements • 7:15 PM - **Second Talk: Swift on Android** (Virtually from NYC) • 7:45 PM - Networking **First Talk Description:** • From Shared Logic to Shared Pixels: A KMP & CMP Deep Dive Clinton Teegarden Explore the complete lifecycle of Kotlin and Compose Multiplatform, tracing the journey from compiler mechanics down to the practical day-to-day developer experience. By building a Flappy Bird-style game, we'll unpack how shared UI rendering actually works while navigating the realities of iOS interoperability and common architectural gotchas. You'll leave with a clear roadmap for seamlessly translating shared business logic into performant, cross-platform pixels. Clinton is a Distinguished Engineer at Capital One with a focus on Mobile and AI core platforms **Second Talk Description:** • Swift on Android Marc Prud'hommeaux The release of Swift 6.3 features official support for the Android platform. This is the culmination of over 10 years of effort to bring the Swift language to Android, first through a series of independent and uncoordinated projects and then eventually coalescing into an official Android Workgroup under the umbrella of the Swift project. The result is the Swift SDK for Android, a cross-compilation Swift SDK that can be used on macOS and Linux to compile Swift code into the various Android architectures as a native library. But what can you actually do with Swift on Android? Far from being limited to just libraries for sharing business logic between Android and iOS, you can, in fact, use it to build and distribute entire apps. This talk will discuss the various ways in which the Swift SDK for Android can be used to create applications, from the lowest-level manual native interaction with the Android NDK and SDK, to synthesizing Java bindings generated with the nascent swift-java project, all the way up to creating full Jetpack Compose powered apps using [Skip.dev.](http://Skip.dev.) Swift is now a contender among the languages that can be used to build applications for both iOS and Android. While it is a newer entrant compared to the established players like Dart, JavaScript, and Kotlin, it features some distinct advantages that make it worth considering for your next app project. Marc Prud'hommeaux has been developing apps for iOS and Android since 2008, and was the author of the very first ebook reader for the iPhone: Stanza. He has worked in a variety of roles over the years, designing and building apps for giants like Amazon, Bose, and the New York Times. In 2022 he started [Skip.dev](http://Skip.dev) ([https://skip.dev](https://skip.dev/)) with the vision of bringing Swift and SwiftUI application development to Android, and is one of the founding members of the Swift Android Workgroup. He is also the founder of the non-profit App Fair Project ([https://appfair.org](https://appfair.org/)) and an advocate for software freedom.

Bike Lane Brewery Hike - Short (Rating: C)
You must read the following NVHC Sign-in Sheet Statement/Liability Disclaimer, [https://nvhc.com/signin.pdf](https://nvhc.com/signin.pdf) and then answer the question that you will see when you RSVP with "I accept" to be permitted on the hike. This hike runs at 8.90 miles and 380 feet elevation, just at the upper limit for a C hike. We will start at the Bike Lane Brewing &Café, at 11150 Sunset Hills, Reston VA 20190, **at 9.00 am.** From there we will follow the W&OD trail to Sunrise Valley Avenue. There we take a left and walk for half a mile through a residential area, then hitting the Difficult Run trail on Brittenford Drive. After about a mile, the Difficult Run trail merges with the Cross County Trail that brings us to Colvin Run Mill, where we will stop for our break. We may have a quick look at the tunnel to nowhere, to see if the works on the passway have started. After the break we will hike through Colvin Run Mill Park, all the time staying close to Colvin Run. The final part of the hike takes us through Lake Fairfax Park, and then ……. back to the Bike Lane Brewery, where we can rehydrate with noble liquids, maybe sitting outside. The weather forecast for Friday April 24 is promising. Most of the surface is easy going, but there are some rocky parts, especially towards the end. There are two river crossings, one on well-spaced concrete pillars and one on large and well-spaced boulders. Please make sure that you take enough supplies and that you are prepared for the weather: sunscreen or raincoat! **Pace:** 2½ mph when moving. **Leader:** Willem Janssen, cell 202-280-4397 **Rating:** C **Map:** https://www.alltrails.com/explore/map/map-october-23-2024-e3958a8?u=i&sh=g8n9nn **Dogs** are permitted on this hike in accordance with the NVHC Dog Policy.
