I'm going to start doing a few short trips this summer (never toured before), but I can't stand riding on paved roads next to cars all the time. My favorite terrain to ride on is the "fire road": your typical dirt road, access road, unimproved road....whatever you'd like to call it. No cars, lots of trees, easy going.
Anyway, are there maps out there that show these dirt roads and not just the paved roads? I'm in North Carolina, but info about other regions of the country is fine as well. Any help is welcome.
