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!

After a short winter hibernation, we are back for warmer weather events! We'll kick things off with our monthly social at [Rehab Tavern ](http://rehabtavern.com/) located in Franklinton! **Address**: 456 W Town St #460, Columbus, OH 43215 You'll find us at a large table with CAC flyers and placards! We'll be discussing what warm weather events you'd like to see such as hiking, biking, kayacking, etc!

**Summary** Celebrate America's 250th year and the [Columbus Clippers'](https://www.milb.com/columbus) 50th season by watching [Franklin County's](https://en.wikipedia.org/wiki/Columbus_Clippers) best team play the [best game in the world](https://www.brainyquote.com/quotes/babe_ruth_140116) at [one of the ten best](https://www.dispatch.com/story/sports/minors/2025/03/26/huntington-park-voted-top-10-minor-league-ballparks-usa-today-10best-awards/82656048007/) baseball stadiums in the United States in their 2026 home Saturday opener! The first pitch is scheduled for 4:05 p.m. The gates always open an hour before the scheduled first pitch. I'm usually at the ballpark a half an hour before the scheduled first pitch. Clippers' games usually last around two and a half hours. Being a few minutes early will help us secure good seats. **Parking** I personally always like to park in the [McConnell Garage](https://www.google.com/maps/place/McConnell+Garage/@39.9685114,-83.0103938,17z/data=!4m6!3m5!1s0x88388f24145462d1:0x6238c0f0c851ab70!8m2!3d39.9692957!4d-83.0081175!16s%2Fg%2F1jkw6y27y?entry=ttu&g_ep=EgoyMDI1MTExNi4wIKXMDSoASAFQAw%3D%3D). If nothing else is going on in the area, this should be $7. However, I've also seen it be as high as $22. I can't say for certain what it will be for this game, but once I know, I will post in the comments. Alternately, there are other lots in the area you can try which will probably be a few dollars cheaper. [Here is a map](https://img.mlbstatic.com/milb-images/image/upload/q_auto/milb/ernng44ya2xkr4wbheql) of all the garages and lots surrounding the stadium. Keep in mind that many of these are outdoor lots and your car will be out in the elements. If you decide to look for a different lot, I would mildly recommend either the Buggyworks Lot or the Broadbelt Lot, but I have never parked in either of these myself. Although it won't apply for this game, keep in mind that street parking is also free citywide in Columbus on [Sundays and holidays](https://www.columbus.gov/files/sharedassets/city/v/1/public-service/right-of-way-permit/on-street-parking-out-of-service-policy-and-procedure-final-8.15.2022-signed.pdf). **Where We'll Be** Here is a [map of the ballpark](https://img.mlbstatic.com/milb-images/image/upload/milb/qkqohbqjgtx5uwo6zkgn.pdf). We'll be sitting on Level 3 of the [Left Field Building](https://www.milb.com/columbus/ballpark/huntington-park) (aka the "AEP Power Pavilion"), which features a 110 foot bar with six open patios overlooking the field. This area is covered and will be out of any sun or rain that may transpire. If you enter the park through the Center Field Entrance (which is at the intersection of Nationwide Blvd. and Neil Ave.), there will be a door to your immediate right after you enter that leads to a staircase up into the Tower. This door is not well-marked, and if you've never been to Huntington Park before, you may wonder if you're actually allowed to go in and up the stairs. Yes, you are. We'll be on the Tower's "Level 3". I have uploaded to the Photos section of this event page, below, a picture of the sign you want look for after you ascend the stairs, so you'll know you're on the correct floor. **Tickets** Do not buy your tickets ahead of time. They will literally be twice as expensive if you buy them on Ticketmaster. Instead, go to the ticket window near the Center Field Entrance. Buy a *Standing Room Only* ticket (don't worry, you won't be standing), which will cost you a flat $8 with no other taxes or fees. These tickets never sell out, and this is the cheapest way to get into the park. **Carry-Ins** Per the team's [website](https://www.milb.com/columbus/ballpark/a-z-guide): "Soft-sided coolers are permitted in the general seating area [which is where we'll be], but not hard-sided coolers; also no alcohol, glass bottles, or cans will be permitted. SMALL bags or backpacks of food items and beverages in plastic bottles are ok. Reusable water bottles are permitted, but must be empty upon arrival. Diaper bags are allowed." I always bring a disposable plastic bottle of water and refill it as I need at the park. Bottled water at the game is something like 4 or 5 dollars. So if you want a bottle of water, I recommend bringing your own bottle instead of buying it at the park. **Food & Drink** The area we'll be in has burgers, hot dogs, salads, soft pretzels, ice cream, and other sorts of things you would expect at a baseball game. I've posted pics of the menu in the Photos section, below. The burger and fries are $14 plus tax, and they're not bad. (This is what I usually get.) The beer is *really* overpriced. It's like $9, or $20 for a pitcher. If there's some people to help me drink it, though, I'll buy a pitcher of Michelob Ultra. While we'll be on the penultimate floor of the Tower, the top floor (which has a great view, but is fully exposed to the elements) has a [Dirty Frank's](https://dirtyfranks.com/) hot dog stand. I've never gotten anything from there, though I've been told it's good. The Donatos pizza stand is also a very short walk away from where we'll be. I love Donatos, but the pizza is so expensive at the ballpark. It's like $9 for a personal-sized pepperoni. It is good, though. **Peroration** Let's (watch them) play ball!

The Fellowship of the Star Schema: Transforming OLTP Data for Power BI One does not simply build reports on OLTP data. Join us on an epic journey from the depths of raw, normalized tables to the shining halls of a well-modeled star schema fit for Power BI greatness. We will demystify the differences between OLTP and OLAP, walk through star schema vs snowflake (and why Power BI has a clear favorite), and show you the compression differences between normalized and columnar storage that will make you never look at an OLTP model the same way again. We will cover the different types of dimensions, when to use them, and how to handle Slowly Changing Dimensions without losing your mind. You will leave knowing exactly how to identify a bad model, how to convert OLTP data into a clean star schema, and how to forge relationships that rule them all. Whether you are a data wizard, a curious hobbit, or somewhere in between, your models will never be the same.

The market changed—and most investors are still operating like it didn't. Deals that used to work don't. Buyers want different things. And a lot of what's being taught right now is outdated or just wrong. And, since 2011, it's been our job to make sure that our members are armed with the most up-to-date, real-world strategies for building wealth in Central Ohio real estate… …so our mission with this meeting (and every meeting) is to give you the no-hype, warts-and-all info you need to succeed. First, Wholesaling 101—a clear, real-world look at how wholesaling actually works today, what to pay, and how to stay out of trouble. Then, Creative Deal Autopsies—real investors breaking down real deals with real numbers, real conversations, and real outcomes. You'll also get the chance to put the presenters in the hot seat and ask any and every question you have about how they did their deals. You'll learn: 1. What wholesaling actually is 2. How to calculate real offers 3. Where deals are coming from now 4. What buyers want 5. How creative deals are structured 6. What contracts and terms are used 7. What can go wrong—and how to avoid it **Agenda:** 5:00–6:00: Free Light Dinner and Networking 6:00: Earlybird Meeting – Wholesaling 101 7:00: Buy-Sell-Trade (members only) 7:30: Creative Deal Autopsies Members: Free First-time guests: Free Non-members: $35 (or join for $30 instead) Remember, to actually reserve your seat, you have to go **[HERE](https://www.coreerocks.com/Events.aspx?ID=IN-PERSON-in-Columbus-Creative-Deal-Autopsies-Wholesaling-101-14-4-7-2026)** and register on our website!
