A Poetry Workshop
Hey Poetry Lovers!
This group is on a roll. Hereâs the gist:
We meet at the **Capital One CafĂŠ in Chinatown** from **12pm - 2pm** every other week.
For enrichment, we start by reading and reflecting on a **âpublished poemâ**, suggested by someone in the group. No advance preparation is necessary. But feel free to check out some of the poems weâve 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; youâre 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 havenât 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 âDC Poetry Workshopâ, 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 âanyone with linkâ, and copy the google doc link into the Discord chat.
Most importantly, weâre excited to meet you!
Catch you on Saturday,
Diego / Ian / Cayden / Nate / Otasha / Lia / An
Colt Express
We will be playing up to two games of Colt Express. All experience levels welcome. Expect the game teach to start promptly within the first 10 minutes.
On the 11th of July, 1899 at 10 a.m., the Union Pacific Express has left Folsom, New Mexico, with 47 passengers on board. After a few minutes, gunfire and hurrying footsteps on the roof can be heard. Heavily armed bandits have come to rob honest citizens of their wallets and jewels.
In Colt Express, you play a bandit robbing a train at the same time as other bandits, and your goal is to become the richest outlaw of the Old West. The game takes place in a 3D train in which the bandits can move from one car to another, run on the roof, punch the other bandits, shoot them, rob the passengers, or draw the Marshal out of position. The train has as many cars as the number of players, and each car is seeded with gems, bags of loot or suitcases at the start of play.
At the end of the game, whoever fired the most bullets receives a $1,000 braggart bonus, and whoever bagged the richest haul wins!
Find [here](https://www.youtube.com/watch?v=4RCXK0EX4AA&pp=ygUYaG93IHRvIHBsYXkgY29sdCBleHByZXNz) a how to play video on YouTube.
Find [here](https://boardgamegeek.com/filepage/107657/colt-express-game-rules-in-english) the rulebook.
Note: Please remember to update your RSVP if you can not attend the event. By updating your RSVP when you can't make it other players on the waitlist will have a chance to attend. No-shows may make it harder to attend future meetups. Also, all library rules apply to this meetup event. Mainly that no food is allowed in the library. Covered drinks are allowed.

Rock Creek Nature Center Loop to Georgetown and Back with E-bike Lovers
[https://ridewithgps.com/routes/41342369](https://ridewithgps.com/routes/41342369)
17.8 miles paved; lunch @ 9.5 miles @ Fletcher's Boathouse. Bathroom at start, Peirce Mill, Fletcher's boathouse; Bethesda outdoor pool (port-a-potty).
Arrival is 10:00. Cycling starts at 10:15.
For this e-biking extravaganza we begin at the Nature Center in Rock Creek Park and e-bike down Beach Drive, which is closed to cars. After a short stop at the waterfall and Peirce Mill, we continue on the trail past the National Zoo, take the Zoo Loop, and follow the trail toward the Potomac. After an optional stop at the Georgetown Waterfront, we'll wind our way onto the Capital Crescent Trail going north. Then on to Fletcher's Boathouse for lunch in the park.
After lunch (you bring your own) we head north toward Bethesda, then make our way east through Chevy Chase and back to the Nature Center.
The ride affords ample scenic vistas, multiple Kodak moments, and dare we say it, abundant E-Bike love.
Please bring some snacks, lunch and plenty of water. Our bikes will be always in our sight. No additional locks are required to keep your bike safe on this trip.
The group stops a few times for slower riders to catch up. The distance will be around 18 miles or shorter any time you are fully satisfied with biking for the day.
**Please charge your battery. While much of the ride is flat or a gentle grade, be aware there are some hills on this route. As usual, non-assisted bikers are most welcome.**

Let's have a Laotian lunch at Padaek!
Padaek is a family owned restaurant showcasing Lao and Regional Thai cuisine. Their new location in Arlington Ridge represents cultures through food, inspired by stories and family recipes from Chef Seng Luangrath's grandmother, aunt, and friends passed along in a refugee camp in Thailand. The integrity of Lao and Regional Thai cuisine is further demonstrated through the homestyle setting and art by a young local artist. Laotian food is similar to the cuisine from northern Thailand, but is spicier and more complex.

Did you know that there are atheists everywhere?!?! You may not know it, but we are! We're in your schools, diners, police force, military, government, and some are even still in your churches! So come and join us and meet other local atheists, along with agnostics, heathens, humanists, skeptics, and anyone else who's 'hell bound'!
Vision: a Central Ohio that accepts atheism as a viable alternative in all areas of public and private life.
Mission: grow, support, and provide community for atheists in Central Ohio.
Social meetings held most Tuesdays at a local pub/restaurant at 7:00 PM (and often into the wee hours). Attendees call themselves agnostics, skeptics, humanists, non-theists, deists or even theists. All attendees are welcome but should support our vision.

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 donât 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.
This group is created by the Hubbard Dianetics Foundation of Central Ohio and Church of Scientology of Central Ohio.
