Like I said before, I used to have lacrosse practice on this field right behind the tennis courts. That would be the perfect place for it. It's a big open area, and then, if anyone wanted to play tennis, they could. You might have to call Forrest Park and reserve the spot for that day though. You also might want to have a backup plan in case it rains like a random movie at Union Station. I hate to be a pessimist, but I would hate to see all this planning all go down the drain because of some rain.
