I have a '03 Trek 7500 FX with slick tires. I spend most of my time riding on city streets. I'm going on a trip to rural FL next month. I plan to ride around on mostly paved country roads. However, there are a couple of unpaved sections I'm keen to try. One 4 mile stretch looks especially interesting. I'm expecting packed dirt and gravel, from the little bit I can see on Google street view. So am I in for a painful experience or bike bliss? Would anyone here attempt it?
