Hi, I'm visiting the D.C. area from the 15-21 of October and was looking for a few ideas for places to visit. My girlfriend and I have already decided on the typical government and tourist landmarks, but I was curious about checking out some tennis locations/shops or any other interesting "out of the ordinary" spots. My girlfriend doesn't play tennis, and I she would go crazy if I snuck in a few sets or even worked on my serve during this trip, so I may have to leave the racquets here . Any info that you could provide would be greatly appreciated. Thanks!
