We did part of the broadcast from the Dig Night street race at NRG Stadium a couple of years ago, that was a total shit show on so many levels, and it even had some "organization" to it.
1. The parking lot is going to be WAY short for fast cars. You need lots of real estate for a "safe" shutdown.
2. The surface is going to be way to bumpy, worse than a road. It might be fine for the cone dodgers, but you try to put a race car down that surface that doesn't like bumps bad stuff will happen.
3. Facebook has already killed this. All these mouth breathing, vape sucking, cheeto eating "racers" are already going there to test and the weather isn't even good yet.
4. The city of Columbus will shut this down because the NIMBYs don't want it.
