Check out the site of the Adventure
Biking Association, which promotes cycling around the country and does a lot to help build trails all over the US.
They have developed the National Bicycle Route Network and have a terrific list of
routes and maps for your biking pleasure. You can also
join expeditions or get tips on your technique from their Tour and Instruction area. These are dedicated folks, eager
to spread the gospel of biking, and the site is a great one to check out as we pedal swiftly into summer.
