Cool slide show. I was looking for the Silver Comet Trail, but it wasn't one of them. It's a 100 mile trail that runs from Smyrna, GA to Anniston, AL along an old railroad. http://www.silvercometga.com/

Although it might be considered too busy as there are tons of cyclists out there all the time as well as roller bladers, runners and walkers. It's also a favorite for local time trials as it is relatively flat.
