ISO a tennis court that has a wall I can practice on!

I’m normally free at odd hours, and need a tennis court I can practice at that has a wall. Drove to three parks today and none of them had a wall attached to the court. Most of my friends work during my off hours, so that isn’t an option. Any park recommendations would help! (And no, I don’t feel like practicing in a lot at an autozone, it’s just not the vibe I’m looking for.)
