| I used to love to play tennis, and had a wall to our garage that i could hit the ball against and practice when i was growing up. Now i'm "grown up'" and my house now has no wall :(. Are there any tennis courts that have a practice wall, or any place i can go to hit tennis balls alone? I'm thinking that come spring that might be something great to add to my beginning runner workout to strengthen my upper body! Any ideas on where to go?
