Read & Reflect: A Social Reading Circle.
Shared Pages, Shared Insights.
๐ Do you love reading, but wish you had a structure and a community to share your insights with?
Join our small circle of curious minds (just 4 members per gathering) as we come together for an hour of focused readingโin the calm setting of a library or the cozy atmosphere of a cafรฉ.
Hereโs how it works:
First part: Quiet reading on your ownโbring a book youโre exploring, whether itโs philosophy, history, psychology, literature, or anything meaningful to you.
Second part: We regroup and each person shares key takeaways, insights, or questions sparked by their reading. This sparks a structured yet free-flowing conversation around ideas, perspectives, and personal reflections.
Why join?
Add structure to your reading habit.
Discover new books, authors, and ideas through othersโ choices.
Build real connections by sharing and listening deeply.
Socialize around something meaningful instead of small talk.
Reschedule: Backpack - Mount Rogers (22 Miles) - 3 Days
**IMPORTANT -** If you are not 100% committed please do ***not RSVP.*** No shows will be de-propritized for future events.
We got rained out on Memorial day - so let's try this again on July 4th weekend!
The Mount Rogers/Grayson Highlands loop hike is an iconic section of the Appalachian Trail, located in the southwestern hills of Virginia within the Jefferson National Forest.
This region is best known for its vast mountain views and alpine peaks with **wild ponies** roaming about. This area is also home to Virginia's highest point, Mount Rogers, sitting at 5,729'. This is a premier east-coast backpacking destination, so don't miss this one.
## **Trail Facts**
* **Difficulty Level:** Moderate
* **Length:** 21.4 Miles
* **Duration:** 3 Days
* **Elevation Gain:** 3,898 Feet
* **Bear Canisters:** Not Required
* **Permits:** None

* **AllTrails Map**: https://www.alltrails.com/explore/map/mount-rogers-and-appalachian-trail-loop-958adb5?u=i&sh=rak641
**Trail Details:**
We will meet at The Vienna Metro station on Friday morning at 8am and drive to the Mt Rogers Trailhead (off Rt 603). This parking lot is **NOT** the paid lot near Masie Gap, and so can fill up. I'd like to try to get there as early as possible.
The drive is about 5 hours. I will drive and am happy to have others carpool with me - but please note, I will have my small black labrador in the back seat.
**Day 1**
After we park, we will hike about 7 miles to our campsite, diverting once to summit Mt Rogers. There arent any views here, but it's worth the .3 miles to say you've been to the highest point in VA! We will camp on the first night at the scenic tent sites near the Thomas Knob Shelter on the AT. There is water at this site and we may see wild ponies if we're lucky.
**Day 2**
The second day is about 10.7 miles, which includes spectacular views, unique rock formations and wide open grassy meadows. We will camp near the Old Orchard Shelter. There is a spring with water at this site as well.
**Day 3**
The third day will be a short 3.5 mile hike from camp back to the cars. Getting to the cars early will mean that we should get back to DC around 4-5pm. On the drive home, I plan to stop at Martin's in downtown Roanoke (413 1st St SW, Roanoke, VA 24011).

**Host's Philosophy on This Event:**
The purpose of this meetup is to create a fun and supportive environment where we can improve our skills, enjoy competitive games, and connect socially. While we do aim to play seriously and challenge ourselves, the focus is more on growth and enjoyment than simply winning at all costs. Thatโs why the title doesnโt include โcompetitiveโ or โsocialโโwe want a healthy mix of both. This is a space where you wonโt be judged for making mistakes. ***We do expect you to listen to the organizer if they make suggestions or adjustments***. We also expect a mindset geared toward learning and getting better over time. That said, this event isnโt intended for beginners; an understanding of the game is expected so that everyone can contribute to meaningful and engaging matches. The host holds the right to remove you from the game if they believe that you are at a C level.
**Skill Level:**
1. **If you want to know your level, please see the link below:**

**ATTENDANCE:**
**Player Selection:** Regulars > Your Vibe > Smiley Flaky Ratio\* > Skills > New Members > New Member with a +1.
The host takes attendance very seriously. Please remove yourself from the event (if you can't make it) as early as possible to allow others to join. You will be marked as a ***no-show*** if you don't show up to the event.
One no-show means you will be removed from the group. See the rules below.
**\*The organizers can see the number of times you have attended events vs the times you have dropped out. If your drop rate is more than 50%, you may not be accepted to the going list.**
[Smiley Social Rules](https://docs.google.com/document/d/1HrG35p_0M08leRvCp8XWG3CMkr_GL928XFabl5T6Dvg/edit)
**Q&A**
* Bringing your **dog** is welcome and encouraged.
* *Can I be late or leave early?* The host expects you to be there **on time** and leave on time. If you need to arrive late or leave early, please let the host know in advance.
* *Can I come even if I am not on the going list?* No
* Why max the players at 10 when you can do 6v6? This court is already for 2v2; getting 6 players on each side is overkill.
* How can I become a regular if I don't ever get to attend? You can attend my other events. Show me you have good skills and bring good vibes!

A Workshop to Get Rid of the Negative Emotions and Finally Be Happy
Your negative emotions can significantly impact your life and your relationships. Sometimes couples and friendships break apart simply because people couldn't manage their own negative emotions, such as anger, worries, anxiety, or depression.
In this meeting, you will learn where these negative emotions come from, for you, and what you can do to start healing from them.
YOU CAN DO SOMETHING ABOUT IT!
And you can do it without medications, without suppressing these emotions inside yourself. You don't need to leave your loved ones.
Come to this meeting and learn the answers. Our doors are open.
Refreshments will be served. Call to reserve your seat 202-797-9826.
This group is created by the Dianetics & Scientology life improvement information center in Washington, DC.

From Glen Echo's Charm to the Majestic Great Falls with E-bike Lovers
[https://ridewithgps.com/routes/45899232](https://ridewithgps.com/routes/45899232)
26.1 miles. Lunch is at the Great Falls overlook 18.2 miles into the ride. There are toilets at Great Falls and Fletchers' Boathouse.
We will e-bike from Glen Echo Park in Maryland to the majestic Great Falls. We will be biking on the Capital Crescent Trail, the C&O Canal pathway, and McArthur Blvd with separate biking lanes. This tour captures the essence of adventure and natural beauty.
We will be meandering alongside the serene Potomac River and the C&O Canal, offering E-bike Lovers an unparalleled opportunity to immerse themselves in the lush landscapes that define this region.
Glen Echo Park, with its rich tapestry of cultural and artistic heritage, serves as the perfect prologue to a journey that gradually unfolds into the wild, untamed beauty of the Great Falls.
The route is just over 26 miles on gravel and asphalt. The gravel is compact. If you don't like the gravel on the C&O Canal pathway, this is not your route.
Entrance to the Great Falls National Park is for free as we enter from the C&O Canal.
We park at the large parking lot off Oxford Street, NOT at the smaller lot at McArthur Blvd.
Please bring snacks, lunch and plenty of water.
FYI: Ride With GPS E-bike Lovers Club membership is now for free as [www.ebikelovers.com](http://www.ebikelovers.com/) generates sufficient income from ads to cover the costs.
Here is the link to activate your free membership:
[https://ridewithgps.com/auto_approve/Club/6746/Zwa5jhttF5mJrFbN](https://ridewithgps.com/auto_approve/Club/6746/Zwa5jhttF5mJrFbN)
The group stops a few times for slower riders to catch up.
**REMEMBER:** This is a self-guided event. This event empowers each participant to take the lead, as there are no designated bike leaders within E-bike Lovers. We all embrace the role of leaders in this self-guided experience.
Please RSVP only if you are coming so we know how many E-bike Lovers will participate. We enjoy a nearly 100% RSVP success rate.
Thank you so much for your help!
As usual, non-assisted bikers are most welcome.

A Poetry Workshop
Hey Poetry Lovers!
This group is on a roll. Hereโs the gist:
We meet at the **Capital One Cafรฉ in Chinatown** from **12pm - 2pm** every other week.
For enrichment, we start by reading and reflecting on a **โpublished poemโ**, suggested by someone in the group. No advance preparation is necessary. But feel free to check out some of the poems weโve read [here](https://docs.google.com/spreadsheets/d/e/2PACX-1vSyE_wCLQCPHRrKmN5F9tOIeeRQUZESxjRXGVBoCF2uU8Gm0_d0uECiCBCQXEy6ksxfsBOhtRIOpW3T/pubhtml?gid=0&single=true&widget=true&headers=false%22%3E%3C/iframe%3E). Or submit suggestions for future meetings [here](https://docs.google.com/forms/d/e/1FAIpQLSexGc2Z2Kp6bZW0D3_hfJ7NUUkfNHf7TXX-43FglCeBd9EF2Q/viewform?usp=send_form).
Next, we **share our work and offer feedback**. Depending on attendance, everyone gets \~10 minutes to use as they like. (No need to share, though; youโre welcome to come even if you prefer just to listen.)
We maintain a **Discord server** to help share our work and communicate outside our bi-weekly meet-ups. If you havenโt used Discord before, take a moment to download it and create an account before arriving. When we meet you on Saturday, we will add you to our server, the โDC Poetry Workshopโ, and can help you navigate the app if you have questions.
Finally, if you plan on sharing a poem, consider how you will do so. Some options include:
* Print 5-10 copies to distribute in person
* Take and share screenshots in the Discord chat.
* Copy the poem into a google doc, change sharing settings to โanyone with linkโ, and copy the google doc link into the Discord chat.
Most importantly, weโre excited to meet you!
Catch you on Saturday,

In-Person Event: The Answers to Depression & Anxiety
This is an in-person meeting. At this meeting you will get answers to depression and anxiety. Find out the source of them and how to get rid of them.
Did you know that unwanted emotions like anxiety, depression, unhappiness, loneliness, hopelessness, anger, fear, or feelings of irritation donโt just fall on you for no reason. They are not random occurrences that simply happen to people's minds. They are definitely not due to a chemical imbalance in your brain from some nebulous chemical reaction "by chance".
Your negative emotions are the symptoms of the painful experiences that you have which are not healed, and which are still affecting you.
The effects of these painful experiences are exacerbated by the pressures or difficulties of the other problems in your life.
Come to our Meetup, where we can introduce you to some of the knowledge, tools and techniques of the breakthroughs in the field of the mind that we can apply to this ever important area of life.
Be sure to click on the red "Attend" button below to come to this local event. We look forward to seeing you there.

Stop Guessing: How to Measure and Improve LLM Outputs
Most people use LLMs by feel: ask a question, read the answer, decide whether it โseems good,โ and move on.
That works for casual use. It does not work when you are building software, automating workflows, writing important documents, or relying on AI for anything that needs to be repeatable.
In this talk, weโll look at how to improve and evaluate the inputs and outputs of LLMs using practical measurement techniques. Weโll cover how prompt changes affect results, how to compare outputs, how to build simple evaluation sets, and how math-based methods like similarity scoring can help you move beyond guesswork.
This will be beginner-friendly, so even if you don't know anything about AI, you should get something out of it. However, this will be a little more technical than our intro talks. You do not need to be an AI researcher, but programmers and technically curious attendees will get a lot out of it.
Weโll cover:
* Why โit looks goodโ is not enough
* How to improve prompts by changing the input, context, and constraints
* How to compare LLM outputs more systematically
* Basic evaluation techniques for accuracy, consistency, and usefulness
* How embeddings, cosine similarity, and scoring can help evaluate results
* Where automated evaluation works โ and where humans still need to stay in the loop
By the end, youโll have a practical mental model for treating LLMs less like magic and more like systems you can test, measure, and improve.
LOGISTICS AND PARKING:
The talk starts at 7:00 PM. The first half hour is reserved for everyone to get set up and mingle. Free pizza and drinks!
The cheapest parking option is to find street parking, which will only cost you a few bucks. Otherwise, park in the nearby veteran's museum lot for $8. It's highly recommended you avoid the nearby $15 garage parking.

You need PEOPLEโwho can advise you, partner with you, bring you deals, and buy deals from you.

CBusData - Highlights and Hidden Gems in SQL Server 2025
Highlights and Hidden Gems in SQL Server 2025
With so much emphasis on cloud data platforms and AI these days, SQL people can feel left behind by all the marketing hype. SQL Server 2025 was officially released in November of 2025, though, and contains a ton of improvements that will make our SQL Server deployments a bit faster, better, and more secure. There are even more improvements tucked into the release that never made a marketing blog or press release that you'll likely be learning about for the first time in this session!
Join this session to learn about what makes your high availability a little more available, your performance a bit more performant, and your database more developer and app-friendly. Come spend an hour with SQL people talking SQL Server 2025 โ the good, the "not quite ready for prime time", and the hidden awesomeness.
