Wet Dog Tavern
Brisk 3- to 4-mile urban hike starting and ending at the Wet Dog. Adult beverages to follow the hike. Closest metro U Street.
The Great American State Fair Share
This epic event will run for two weeks, I want to create a MeetUp giving others, like myself, a way to meet new friends and get out there for any day you have available. Each day will be a duplicate event, giving everyone the ability to sign up for the day they have free. I will not be at every event as I work three days a week, but I will put in the messages the days I'll be there. The Metro Smithsonian is a great place to meet since it's right at one of the two entrances. The only two entrances are at 12th and 4th and Jefferson. If you want to go to one or several of the days just hit the attend and message those who are also planning on attending that day. You can coordinate the times as well. Let's make new friends and experience the 250 anniversary of our country.

Tuesday Night Skate (TNS)
Hi everyone! Tuesday Night Skates are in full effect! Meet every Tuesday outside of the NOMA-Galladudet U Station at the North entrance (1305 2nd St NE). We will head out at 7pm sharp for an 8 mile skate followed by pizza! We'll skate up the Metropolitan Branch Trail to the Ft. Totten Metro station and back down the trail to M St NE for pizza at Andy's. See ya there! This skate is led by Asher and myself. 🛼
This ride is BEGINNER FRIENDLY! While the full ride is 8 miles long, you have the option to tap out at one of the three red line metro stations along the route in both directions. You'll also have an opportunity to learn new skills and practice drills with the skate leaders at our regroupping spots along the route. The tap out points are as follows:
2 miles: Rhode Island Ave Metro
2.5 miles: Brookland Metro
4 miles: Ft Totten Metro
6 miles: Brookland Metro (on the way back)
7 miles: Rhode Island Ave Metro (on the way back)
8 miles: Andy's Pizza
This is a great way to test and build up your endurance while skating! At least one of the skate leaders will skate at your pace, so you'll never be left behind.
Join us at Andy's Pizza afterwards for a FREE slice of pizza with the purchase of any alcoholic beverage or N/A lemonade!

If we need to cancel one week due to weather or other reasons, we'll update the event page in advance.
Fast-paced small sided soccer
This game is located at the DC/Maryland Border in Silver Spring.
We'll use the Tennis Court at Juniper blair where there are Night Lights shining on an enclosed arena. This area is enjoyable because it allows for more touches on the ball, with more movement around the field.
THIS IS ON A TENNIS COURT. WE DO NOT WEAR CLEATS. WE WEAR FUTSAL SHOES, TENNIS SHOES; ANYTHING WITH NO SPIKES. Pinnies and goals will be provided. Bring a ball if you have one.
We usually get 10+ more players not on meetup — we'll add those to whatever we get here and see if we can have a game.
More than competitive, we all want to play good futsal and make it fun and entertaining for all. No warm sided matches here — new and advanced players are welcomed. Here, we want to get active and have fun in the evenings after work

**Ride Level Chart**
**++++++++++++++++++++**
NoVA CBG tries to accommodate all levels of cyclists by offering different types/levels of rides. We just ask that you come to the ride that suits your current riding ability the best.
* Introductory Level: If you haven't ridden a bike in a number of years (or are uncertain of your abilities on a bicycle).
* Beginner Level: You can ride for 10+ miles at a pace of 10+ to 12+ mph with potentially minor hills involved.
* Medium Level: You can ride for 20+ miles at a pace of 13+ to 15+ mph with potentially moderate hills involved.
* Advanced Level: You can ride for 20++ miles at a pace of 15+ mph with potentially major hills involved.
Both Medium and Advanced Levels might require handling various challenges such as reading cue sheets, using a Garmin or navigation app, night riding, out of town travel, or any other odd cycling situations.
**++++++++++++++++++++**
**The Fine Print:**
**++++++++++++++++++++**
An RSVP of 'YES' is your digital signature and means you have read and understood MEETUP.com's:
* "Terms of Service : Section 6. Release " found at https://www.meetup.com/terms/
* NOVA-CBG's "Assumption of Risk Agreement" found @ https://www.meetup.com/novacbg/pages/1942951/NOVA-CBG_Waiver/
Helmets are required to participate in all NOVA-CBG rides. NO exceptions. All riders ride at their own risk and with the understanding that cycling is an inherently dangerous activity. When coming to the meetup you do so voluntarily and are ready and able to participate in the ride as described under the conditions of the day.
Be on time for the "pre-ride" preparation. If you do not attend the pre-ride preparation you will not be allowed to participate on the ride. Again, no exceptions.

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.

Stop Guessing: How to Measure and Improve LLM Outputs
Most people use LLMs by feel: ask a question, read the answer, decide whether it “seems good,” 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, we’ll look at how to improve and evaluate the inputs and outputs of LLMs using practical measurement techniques. We’ll 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.
We’ll cover:
* Why “it looks good” 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 — and where humans still need to stay in the loop
By the end, you’ll 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.
Picnic with a Purpose: Real Estate Networking That Actually Pays Off
(Note: RSVPing here on meetup does NOT reserve your seat. To do that, you’ll need to register at our website, [HERE](https://www.coreerocks.com/Events.aspx?ID=Picnic-with-a-Purpose-Real-Estate-Networking-That-Actually-Pays-Off-14-7-7-2026).)
Real estate is a proven wealth-builder—it has been for generations.
But it’s not a solo sport.
You need PEOPLE—who can advise you, partner with you, bring you deals, and buy deals from you.
We’re all about bringing you the best, most active, most got-your-back people in Central Ohio, which is why our July meeting is all about real conversations with real investors at our annual Picnic with a Purpose.
This is where:
* Deals get discussed
* Partnerships get formed
* Funding relationships start
* Problems get solved faster
Bring your family. Build your network. Strengthen the relationships that actually move your business forward.
Members and first-time guests are free. Returning guests are $35.
Location is a local park and will be shared after registration.
Space is limited, so you’ll want to secure your spot now.
Remember, to actually reserve your seat, you

Powell Gold Star Referral Club Meetup
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!
Data & Analytics Wednesday - Learning from Everyday Data
**Practical Curiosity: Learning from Everyday Data**
How do we actually get better at utilizing our day-to-day data? Fancy dashboards and complex models might look nice and draw attention, but that’s not where most of us spend our time. In fact those shiny outputs frequently sit unused, while the real insights are drawn from the analyst’s daily practice.
Sometimes it’s as simple and as powerful as noticing that a segment is shrinking, a channel is underused, or certain links keep getting all the clicks. There’s many different places that the spark of insight can come from, but you have to keep your head in the data and know where to look.
In this session, we’ll explore real-world examples of how segmentation, testing, and click behavior can uncover practical digital marketing opportunities. You’ll leave with inspiration for your own use cases, along with a few simple ways to ask better questions, spot meaningful patterns, and make smarter decisions without overcomplicating it.
**About Our Speaker:**
[Elaine Armbruster](https://www.linkedin.com/in/elainearmbruster/) is a Director of Digital Experience at the [American Diabetes Association](https://diabetes.org/), where she focuses on using data and insights to create smarter, more effective digital experiences. A lifelong Columbus resident, she has built her career in email marketing and the broader digital user journey, and is finding she most enjoys working in the messy middle where systems, data, and big ideas don’t quite line up yet.
