Because I am interested the Great Divide route, I watched a documentary about it. The documentary was about riding on a mountain bike. Started to do some research for the route and found this Association's web site.

http://www.adventurecycling.org/routes/network.cfm

"Adventure Cycling's Routes & Mapping Department carefully links together rural roads to create low-traffic bike routes through some of the nation's most scenic and historically significant terrain."

The site has the divide route and a whole lot more interesting routes, including GPS files.

Great find! If I wasn't going to Egypt in March, I would be planning one of the east coast rides for sure. I'd love to do the Grand Canyon ride. I'm a desert lover stuck temporarily on the east side. When do you think you'll be making the trip?
