Bring your lights for the “Friday Night” Skate! **Join us for the Friday Night Skate!** See the monuments of DC all lit up at night! We will meet at the National World War I Memorial “Pershing Park” at 7pm. We’ll warm up with a nice easy skate to the Capital and skate along the mall and museums to the National Monument. We will then head to the Lincoln Memorial through the World War II Memorial. Those interested in just a 5.5 mile skate can backtrack to Pershing Park. The group will then proceed from the Lincoln to Haynes Point via Ohio Drive with the option to take the 3 mile loop (12 mile total skate) or sit by the water and enjoy the crisp air (8.5 mile total skate.) There are three options to loop back to the Pershing Park WWI Memorial and our path back will depend on the preferences / skill of the group. The skate is mostly flat on good pavement with a small slope coming down from the Washington Monument and a 40 yard small slop from the Lincoln to Ohio Drive. If skaters are more advanced we will cross the 14th St bridge, enjoy a few up and down hills and finish with a downhill through the 12th St. tunnel. Please feel free to jazz it up with lights, I wear a helmet bike light, a fun set of lights and lighted wheels! Wear your lights so you have fun, can see and be seen! In case of bad weather, I will cancel the skate by 6pm on this post. **Of course, all skating is at your own risk.**

Meet in the parking lot of the Handy Bikes Service Center. At the start of each ride, we'll go over introductions to have a sense of participants' cycling experience. Over the course of our rides, we'll address the following: group riding dynamics; safety (ABC check & trail hazards); gear shifting; hill climbing; audible and hand communication within the group, with other trail users, and automobile drivers; what to bring on each ride; etc... Bring your questions, water & a snack. When it starts getting dark earlier, we'll need lights as well. Helmets a MUST. If you can, and especially if you've had issues with your bike, come a bit early to have it looked at ahead of the ride. PS - all levels are welcome to join, however, be mindful that if you are an experienced rider, please be prepared to ride at the pace of the newest rider in the group. Each week, depending on who's in attendance, and participants' riding ability/comfort level, we may do skills practice as a group in the parking lot or at the west end of Wheeler Ave. Once everyone is comfortable, we'll go for a ride on local trails and neighborhood streets and finish back at the shop. Happy Pedaling !! \~Maya

This is one of my fav hikes that combines very scenic valley and river views. We'll start with the Gold Mine trail which runs along the bluff above Great Falls. We'll then hike the Billy Goat A trail, which is one of the most scenic hikes in Maryland. A large part of this hike is scrambling over boulders and rock faces. It is a challenging hike that has very scenic views of the river. The total distance will be 6 miles with about 500 feet of elevation gain. We'll hike at a slightly faster pace, and it should take about 3.5 hours. This hike is not for beginners. Please only RSVP if you hike or walk at least 6 miles per week at a faster pace. If you can't keep up, we will leave you behind, so it's your responsibility to know the route and how to get home on your own if you have to. After the hike, we might go grab a bite at Fish Taco, 7945 Macarthur Blvd, Cabin John, MD 20818 Parking: \-\- The closest place to park is in one of the small lots on the left side of MacArthur Blvd directly across the street from Old Anglers Inn\. But these lots are often full\. \-\- The best place to park is on the street on Stable Lane\. Stable Lane is just past Old Anglers Inn on the right\. \-\- You will also see a lot of cars parked on MacArthur Blvd even though there are "No Parking" signs\. I've never seen anyone towed or ticketed for parking on MacArthur Blvd\, but you're on your own there\. Note that this event is cross posted with the Fast and Fun Hikers meetup group.

**EMPTY-NESTER LADIES! Come join me for the Great Falls Overlook via Billy Goat Trail, Section A.** This is a 4.7 miles and rated "Hard" on All-Trials. Plan for 3+ hours. This is a challenging hike; not for beginners. It includes boulder scrambles, rock-to-rock hopping, and a slanted rock face scramble. Note there are several hand and footholds on this face for grip and security. If you'd like more assurance, as you determine whether to come along, consider Googling this trail or check it out on AllTrails for a good visual. There is an earlier exit point, making the hike 2.9 miles. **Note: This is YOUR hike!** If you want to join us, but are later not feelin' it, cut out earlier and create a day that brings you joy at your own comfort level. There are plenty of side trails and stops to take in the views, ensuring an awesome day! “Never be afraid to try something new, because life gets boring when you stay within the limits” * **Where to meet:** Great Falls Tavern Visitors Center entrance, Lock 20 along the C&O Canal in Potomac. * Parking is $20 per car, which you will pay at the ranger's booth. * **What to bring:** "Grippy" trail runners or hiking boots, a small backpack to carry personal items, water & a snack to eat when we stop to rest. * **Note:** You will need hands for at times, so trekking poles may be cumbersome. If you feel more comfortable having them, plan to attach them to your backpack when necessary.

As a reminder, since Freedom Plaza is under construction, we will meet at the plaza in front of The International Trade Center near the National Children's Museum (on Pennsylvania Ave). We'll begin with going over a few drills (varies week to week). The skills we drill will be for the first 30 minutes. For the second half, we will casually skate down the bike lanes on Pennsylvania Avenue from the plaza to the U.S.Capitol and stop at 3rd St. and then skate back the same route. This route is about 2 miles in total and is perfect for those who are new to skating in the city but feel comfortable on skates in a parking lot or roller rink. This is also great if you wish to start with shorter routes to increase your physical fitness or stamina for some of the other routes. This is an excellent opportunity to prepare to skate with others on the road. You will also get to meet skaters who will arrive for the Intermediate and Advanced skate routes following the introductory skate. This is great training to feel prepared for the Tuesday Night and Friday Night Skate! Route: [http://www.gmap-pedometer.com/?r=7653831](http://www.gmap-pedometer.com/?r=7653831) Inline skates (rollerblades), roller skates (quads), bicycles, unicycles, skateboards, longboards and other similar modes of transportation are welcome to join.

**Billy Goat A, B and C, a Challenging 10.5 Mile Hike** SEE IMPORTANT INFORMATION ON REGISTRATION UNDER "NOTES." Located within the Chesapeake and Ohio (C&O) Canal National Historical Park, the Billy Goat Trail is one of the most famous hiking circuits in the Washington, D.C. metro area. Split into three distinct sections—A, B, and C—it offers a variety of terrain ranging from technical rock scrambling to peaceful woodland paths. We will hike all three sections. Section A is the most famous and difficult portion of the trail. It is renowned for its rugged terrain along the edge of the Mather Gorge and spectacular views. Expect heavy rock scrambling that requires the use of both hands and feet. The highlight is the "Traverse," a 40-foot climb up a near-vertical rock face at a 45-degree angle. Section B offers a transition between the intensity of Section A and the ease of Section C. It is currently a favorite for those who want a river experience without the vertical intensity of the northern section. The trail winds through silver maple forests and across small rocky beaches. It feels more secluded and offers several spots to sit by the water's edge. Section C is ideal for birdwatchers and hikers looking for a scenic but low-impact outing. This section is heavily forested and features several vernal pools (seasonal ponds) that are home to rare plants and amphibians. It is the least technical of the three sections. It offers excellent views of the Potomac River through the trees and access to several sandy floodplains. This is a challenging hike due primarily to the A section. Sturdy hiking boots with non-slip treads are a must. And be prepared to put your rock scrambling skills to a test. Please do not attend this hike unless you are skilled at rock scrambling. Dogs are not permitted on this hike due to the restrictions of Billy Goat A. **Time to Meet**: Please meet at 8:45 for introductions and sign in. We will start hiking promptly at 9:00 **Contact Information**: Please use the comments feature for routine comments and questions. The hike Leaders is Christa (410-610-6254) and Tim (202-744-0289).

We meet at lunch each week and each meeting follows a fairly organized agenda. First all participants pass their business cards around. Then each member and guest is invited to give a one-minute overview of their company and what is a perfect referral for the week. We always have a 10 minute presentation from one of the members about their business in more detail. And finally we pass referrals. You're welcome to visit. Nobody is ever put on the spot. Bring plenty of cards!

Session Abstract ### Data Cleansing using Data Bricks Machine Learning is highly dependent on adequate data. Not only does quantity matter, but more importantly quality. In this session we’ll cover how to build a custom automated process using Data Bricks. This will provide methods for cleaning data in a data lake using functions in Azure. \*Please note, that we will be using Microsoft Teams for the online portion of this meeting. You may want to join a few minutes early to ensure you do not have any issues. If you are attending in person, there are large TVs at the office, and you do not need to bring a laptop or use Teams.

Bring your Raspberry Pi, Arduino, microcontroller, or any other electronic project and join fellow electronics makers for a night of creativity and collaboration! This session is open forum to share your current projects—whether complete or in progress, it’s all interesting! Whether you’re deep into embedded systems, exploring new ideas, or just getting started, you’ll find a welcoming space to collaborate, share, and get inspired. **New to electronics or curious about tinkering?** You’re absolutely welcome. If you’re a beginner and want to experiment, I’ll have a couple of starter kits available so you can try things out—whether that’s blinking your first LED, putting something on a display, or experimenting with simple sensors. No pressure and no experience required—just an interest in learning and building. While we continue to pursue a more permanent venue for this Meetup, we’ll be using public library facilities based on availability. This session will be at the Worthington Park Library in the Olentangy Meeting Room.
