Game. Set. Match. Traditional Cache

Game. Set. Match. Tennis anyone? Well, once you've won this "cache match," you may want to hit the tennis courts for a little fun. You won't be to far from the cache when you are on the courts! Have fun playing tennis, enjoying the playground, hitting the soccer ball, and having fun at this great park! Oh yeah, and find that cache!

You are looking for a green lock and lock container which will hold small tradeables and trackables. Be careful for muggles while searching.  I was nervous leaving this one where it is, but thought it was a pretty good fit! :)   Hint is a sure spoiler!
