Maybe 10%. I have Blanket’s Creek in my backyard and Rope Mill is about a 15-minute bike ride away so I am a bit spoiled but I like the fact that I don’t have to drive to those trails. However, it is completely worth it to drive up to the N. Georgia mountains for about an hour for a multi-hour MTB ride. I usually like to ride for twice as long as I drive as a rule of thumb. The furthest I will drive for a day trip is about 2 hours to Chattanooga’s Raccoon Mtn., also well worth the drive.
