Coal Creek is relatively close to my place, so I go there every now and then. It has everything from gravel roads to ridiculous rock crawler trails. It has a big well run campground (Windrock) also. The place, like so many others, is a haven for ATV's now. Most of the trails are on the rough side. The place is huge.
You'll find more dedicated trail bikes than dual sport bikes there because of the terrain.
I don't have any more pix but you can find many youtube videos of the more popular trails, some with crashes of motorcycles to 4X4's.
I would like to try Brimstone later this year along with Royal Blue.

Where do you like to ride in the Gainesville area...my old stomping grounds? Have you ever ridden the Osceola Forest? I keep wanting to try it out.
