This trail is approximately 23.2 miles with two short but steep inclines and one very shallow water crossing. It took considerable time to design this route, showing the best Reston offers. Our challenge was to cross the Dulles Access Road in an e-bike-friendly way. Most miles are on protected cycling paths, including the W&OD trail. Even if you live in Reston, most connecting trails may be new to you. Just some 30 minutes from Washington DC is Reston. We will be e-biking from the Water Mine Family Swimming Hole to Reston in the vicinity of Reston's man-made lakes. Reston is a recently established urban area. It was founded in 1964 to revolutionize postwar urban planning. It is known for its two golf courses, lakes, ponds, a high density of trees, and open spaces. We will visit the Vernon J. Walker Nature Education Center during lunch. The trail is on asphalt roads and paths with occasional short, but steep inclines and declines. Please bring snacks, lunch and plenty of water. **Free Ride With GPS for E-Bike Lovers** The Ride With GPS E-bike Lovers club membership is now free as www.ebikelovers.com generates sufficient income from ads to cover the costs.

Just good ole Ultimate Frisbee. Tons of fun. Great group. No stacks. No pick calls (but no picks!!!). Fair warning to those totally new to ultimate: it's a lot of running. \*\*Please pay close attention to the rule #6 listed below. *What to DEFINITELY bring* 1. Running shoes/Cleats 2. One white shirt *and* one dark shirt !!!! See this one !!!! \-\-\- IMPORTANT you can play both dark and white so we can make teams when we get there; just pickup after all 😎 3. Water *What you can ALSO bring* 4\. Snacks & Drinks 5\. Gloves \(winter\) 6\. Sunscreen \(summer\) 7\. Sunglasses 😎 House Rules - 1. Starting Play: Each point begins with both teams lining up on the front of opposite end zone lines. The defense throws ("pulls") the disc to the offense. 2. Scoring: Each time the offense catches a pass in the defense's end zone, the offense scores a point. The teams switch direction after every goal, and the next point begins with a new pull by the team that just scored. 3. Movement of the Disc: The disc may be advanced in any direction by completing a pass to a teammate. Players may not run with the disc. The person with the disc ("thrower") has ten seconds to throw the disc. The defender guarding the thrower ("marker") counts out the stall count. 4. Change of Possession: When a pass is not completed (e.g. out of bounds, drop, block, interception, stalled), the defense immediately takes possession of the disc and becomes the offense. 5. Substitutions: Players not in the game may replace players in the game after a score and during an injury timeout. (Modified depending on the number of the attendees) 6. Non-contact: Players must attempt to avoid physical contact during play. Picks and screens are also prohibited. 7. Fouls: When a player initiates contact that affects the play, a foul occurs. When a foul causes a player to lose possession, the play resumes as if the possession was retained. If the player that the foul was called against disagrees with the foul call, the play is redone. 8. Self-Officiating: Players are responsible for their own foul and line calls. The host will also step in if it is needed. Please message the event host for any questions or concerns. \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- **Smiley Social documents:** 1.

Similar to our "Beginner Ride", a casual, on-road-avoiding, cycle-path-winding, beginner friendly, group ride. The ride will be led by Maya and Angie, who have a combined 50 years of cycling experience. This is a no drop ride with an average speed of 7- 12 mph. Please bring a helmet, lights, a snack, hydration and wear appropriate clothing for cooler weather (cotton is not your friend in cooler temps and we will be riding in the dark). The ride can be tailored to the skills that attendees want to master, i.e- drinking from water bottle while riding, making tight turns, riding in a small group and cycling etiquette. We will be riding mainly on trails, streets as minimally as possible, and sidewalks only when necessary. This ride is perfect for someone who hasn't ridden in a while and wants to get some easy miles on the saddle; not just for newbies. If you have not ridden your bike in several weeks, months or years, please have a safety check done before the day of the ride. We are just here to have fun.

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.

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.
