Short North Street Skate | Weekly Rollout
Short North Street Skate | Weekly Rollout
Short North Street Skates return Saturday, April 4 and we’re excited to get back rolling together. These weekly rollouts are a chance to move through the city as a group, build community, and create more visibility for skating and small-wheeled movement in Columbus. Details: Meet: 1160 N High St 9:30 AM meet 10:00 AM rollout All wheels welcome We’ll be skating through the Short North and surrounding areas at a steady, social pace. Routes will use a mix of streets and bike lanes, so comfort navigating the city is helpful, but you don’t need to be an expert. If you’ve been meaning to come out, this is a great place to start. Come solo or bring a friend!
Humanist Program
Humanist Program
The Humanist Monthly Program is our longest running event and still a community favorite. In the old days it used to be called "Going to HCCO" and we still like to think of it as our flagship event. We will be hearing from Becca Powell, Director of Advocacy and Outreach at Unchained At Last, an organization whose mission is dedication to ending forced and child marriage in the United States through direct services and systems change. Unchained At Last's mission clearly meshes and addresses several of our Humanist Ten Commitments. Becca will educate us about an issue many of us may not be familiar with--but should be. Food and drinks will be provided at the event. Feel free to show up a little bit early to hang out and talk. Going forward our meetings will be hybrid. You can meet us in-person or attend online Join Zoom Meeting [https://us02web.zoom.us/j/87836564953?pwd=4Mi57ElZkDIFlb1fnlNwOJ0NiOK4tP.1](https://us02web.zoom.us/j/87836564953?pwd=4Mi57ElZkDIFlb1fnlNwOJ0NiOK4tP.1) Meeting ID: 878 3656 4953 Passcode: 760812 One tap mobile +19292056099,,87836564953#,,,,\*760812# US (New York) +13017158592,,87836564953#,,,,\*760812# US (Washington DC) The formal presentation will start at noon

Fun & easy way to play more tennis (read event description)
We’re still working to get more people into these Meetups, but our goal is to give PlayYourCourt members a few social tennis outings each week in addition to your practice sessions and Challenge League matches. These Meetups are co-ed, super laid back, and all skill levels are welcome. Post your skill level and a suggested court in the comments section so we can round up as many players as we can for some tennis fun! Also, if you’re looking to meet new practice partners or play some matches and you aren’t already in the PlayYourCourt Community, you can go here to see what we’re all about and sign up: https://www.playyourcourt.com/tennis-community/columbus-oh/meetup/ If you love tennis, we’d love to have you!

Contra dance with Big Scioty April 11 - Clinton Heights Lutheran church
Contra dance with Big Scioty April 11 - Clinton Heights Lutheran church
**Caller: Kim Thompson** **Band: Full Moon Country Dance Orchestra** **Clinton Heights Lutheran Church** **15 Clinton Heights Ave, Columbus, OH 43202** WHAT IS CONTRA DANCING? Picture the Grand Ball scenes like you’ve seen in period films such as “Pride and Prejudice”, where the dancers are lined up in long lines, across from each other. That’s English Country Dancing, the predecessor of contra dancing. Now, add moves like “swing your partner” and “do-si-do,” like you’ve seen in square dancing. Set it to fabulous, high energy, live music with fiddles, guitars, percussion and more, alá “Riverdance.” Finally, set the whole scene down in the middle of Woodstock, with a hip, groovy atmosphere, a bit of tie-dye, and hints of counter-culture attitude. THAT’s Contra Dancing! Wear cool and comfortable clothes (you will get warm) and clean shoes that won't mark up our nice wood floor. Be sure to come for the beginner's lesson from 7:30 - 8:00, followed by dancing 8:00 - 10:30. All dances are taught; we will help you learn! Beginners always welcome, no need to bring a partner. Cost is $10.00 adults, $5.00 ages 12-26. Under 12 free. Free parking in church lot. For more information contact me or check out our website: [www.bigscioty.com](http://www.bigscioty.com/) Please bring your own refillable water bottle.

If you can’t attend, please change your RSVP to no. This helps anyone who is waitlisted and it allows me to have an accurate count of attendees as our space is quite limited.

Disc Tues / Choose Your Movie: THE CHRISTOPHERS vs NORMAL at the Gateway!
Disc Tues / Choose Your Movie: THE CHRISTOPHERS vs NORMAL at the Gateway!
Join us as we get together for a Discount Tuesday / Choose Your Movie event to see your choice of two great new films! Option 1 (and the one I'll be seeing) is the top-reviewed comedy-drama, THE CHRISTOPHERS! The film is set in the art world and follows the estranged children of a former artist who hire a forger. It is directed by Steven Soderberg, stars Ian McKellen and Michaela Coel and has been earning rave reviews on the indie circuit. Option 2 is the latest action-thriller starring Bob Odenkirk, NORMAL! The film follows a temporary small-town sheriff who uncovers dark mysteries after a local bank robbery. Here are descriptions, trailers and our plan for this event: THE CHRISTOPHERS: The children of a once famous artist hire a forger to complete some unfinished, long ago abandoned canvases so they'll have a better inheritance when he dies. It is directed by Steven Soderbergh and stars Ian McKellen, Michaela Coel, Jessica Gunning and James Corden. BUZZ & ACCLAIM: The film is earning an excellent 97% positive rating on Rotten Tomatoes where critics call it a “dynamic, emotional and surprising journey” and a “compelling chamber piece that works like intellectual comfort food.” Others call the film, an “incredibly funny, comedy drama with plot reversals that make it feel like it’s on the verge of a thriller!” TRAILER: https://www.youtube.com/watch?v=H79-EqzmdwY&t=20s NORMAL: This action-crime-thriller follows a man who comes to the sleepy town of Normal, Minnesota to serve as the temporary sheriff. But a bank robbery leads him to a criminal underground reaches throughout the entire town. The film is directed by Ben Wheatley and stars Bob Odenkirk, Henry Winkler and Lena Headey. The film comes from the same team that brought us Nobody and the John Wick series, so expect an over-the-top, action-filled thrill ride! TRAILER: https://www.youtube.com/watch?v=Rmm-lM33Qw0&t=19s PLAN: We’ll plan for a 7pm-ish showing of both films and will meet in the lobby area about 30 minutes before showtime. Once showtimes are announced, advance ticket purchase is advised (GFC website preferred)! Please list your movie of choice and seat number in the Comments section of this event. Showtimes and complete details will be confirmed/announced as the date gets closer. PARKING: Close, convenient parking is available in the nearby garage (located between 9th and 11th, just off High St). Bring your ticket with you and have it validated at the theater and for $2, you’re covered for the night! Look forward to seeing you there, Dan

This session introduces Squad: an open-source framework for multi-agent orchestration that lets you define teams of AI agents with specific roles, responsibilities, and expertise. We'll progress from Copilot basics to the Copilot CLI, explore how Agents add autonomy, and see how Instructions and Skills let you customize agent behavior. Then, the climax: a live demo where a Squad team of 3 agents (Lead, Developer, Tester) stands up and builds a working application in real-time, showcasing true multi-agent collaboration. Whether you're new to AI or exploring how to scale your use of Copilot, this session will show you what's possible when agents work as a team. **YouTube Link** TBD
