dingster, the Bike Doctor is less than a mile from Value City. If you get off 270 at exit 31A and head north on 85, the Bike Doctor is in the Evergreen shopping center on the left. It's the same shopping center as Gold's Gym, Common Market and Burger King, right before you get to Wal-Mart. Here's a map. Very easy to get to, which is why I've been going there so much lately.

Velobambina, this would be way outside the Beltway, but it's oh, so pretty out by Harper's Ferry. The river and mountains are just gorgeous. It could be a terrific day trip!
