Yes, 2 and you can dream it up and lay it all out by yourself. Once it's ready to go you just call in the Cavalry. I wish I knew how KC does it, but I'm just not that organized. Anyway, a tennis court is the way to go for sure. Good concrete. Build where you can though. You don't even need a slab if you want a bowl.
OKC - 10 Penn (NW 10th and Pennslyvania) named after the location. The Grindline guys were scared of the "zombies". The regulars suck, but so do the regulars at the municipal skateparks. I prefer the street people to children myself. Instagram hashtag #make10penngreatagain
Our other DIY is on a tennis court. It's called the Licoln Courts because it's by Lincoln Blvd. That's all the direction you're getting. I want to keep Lincoln from being trashed up and blown out by skatepark types. They come, leave trash, grafitti something, break something else, and maybe take something. They are better off at municipal parks. It is open. We don't kick people out. I'm just not telling anyone who asks where it is. If you skate OKC you should already know where it is. If you don't, then skate more. Anyway, this may be a clip.
