**Caller: Richard Ades** **Band: The McKenzies** **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.

We will meet next to the restrooms at the [Big Meadows Picnic Area](https://www.metroparks.net/wp-content/uploads/2022/06/HBK_Web_1980.png). They're all the way at the back of the park, and they can be found at coordinates [40°09'06.6"N 83°02'30.2"W](https://www.google.com/maps/place/40%C2%B009'06.6%22N+83%C2%B002'30.2%22W/@40.151828,-83.0423587,214m/data=!3m2!1e3!4b1!4m10!1m5!3m4!2zNDDCsDA5JzA4LjAiTiA4M8KwMDEnNDUuMSJX!8m2!3d40.1522222!4d-83.0291944!3m3!8m2!3d40.151827!4d-83.041715?entry=ttu&g_ep=EgoyMDI0MTIwNC4wIKXMDSoASAFQAw%3D%3D) (near the playground and the zip line). We'll hike about 5 miles at [Highbanks Metro Park](https://www.metroparks.net/parks-and-trails/highbanks/) on the Dripping Rock and Overlook Trails. Afterward, we'll head over to [Olentangy River Brewing](https://www.olentangybrew.com/) for drinks, coffee, or food (their Sunday [food truck](https://www.olentangybrew.com/eventsandfood) is Venezuelan and always gets good reviews). The actual address of the brewery is [303 Green Meadows Dr S, 43035](https://www.google.com/maps/place/303+Green+Meadows+Dr+S,+Lewis+Center,+OH+43035/@40.1551938,-83.0144045,17.25z/data=!4m6!3m5!1s0x8838f395cef06c97:0xe407de61b3e30069!8m2!3d40.1551765!4d-83.0124352!16s%2Fg%2F11c26jc7j9?entry=ttu). If you can't make the hike, we should be there by noon. **How to find our starting point in Big Meadows:** If you are new to Highbanks, the Big Meadows picnic area is 1.5 miles into the park just after you turn into the park off of U.S. Route 23. That is, after you enter the park, drive a mile and a half into the park. You will come to a crosswalk with a yield sign in the middle of it (this is not to be confused with the first such crosswalk you come to just in front of the Nature Center, which you arrive at maybe a quarter of a mile into the park). Just after this second crosswalk, make a left. Then make another almost immediate left into the parking lot on your left. There you will see the jungle gym and the kiddie zip line to your left. I will be just in front of the restrooms just a bit further down from the jungle gym and picnic shelter; the restroom building will also be on your left.

Session Abstract ### Data Cleansing using Data Bricks Machine Learning is highly dependent on adequate data. Not only does quantity matter, but more importantly quality. In this session we’ll cover how to build a custom automated process using Data Bricks. This will provide methods for cleaning data in a data lake using functions in Azure. \*Please note, that we will be using Microsoft Teams for the online portion of this meeting. You may want to join a few minutes early to ensure you do not have any issues. If you are attending in person, there are large TVs at the office, and you do not need to bring a laptop or use Teams.

Practical AI for Power BI Developers A year ago, “agentic AI” was mostly hype for Power BI teams. Today, it deserves your undivided attention. For Power BI pros, there is now a real opportunity to reduce repetitive development work, accelerate delivery, and help developers do more, but only when strong DataOps practices are in place to make AI workflows effective. This session is a no-nonsense introduction to effective AI patterns for Power BI and Fabric development. Along the way, we will make sense of the growing pile of terminology, including skills, plugins, hooks, and MCP. You will see examples of how modern AI tooling can help with development tasks across Power BI and Fabric, along with the prerequisites, guardrails, and DataOps principles needed to use it responsibly. Whether you're burned out on AI hype or already using Copilot CLI daily, this session will show you the foundations that are finally making AI-assisted development genuinely useful.
