I'm not sure if that road is open since the fires. Hmm.. It's a good question. What kind of tires are you on? If i recall the real bad mud was on the Reiff road section. The Knoxville roads are pretty rocky (mostly planted and not sticking up) but there are some big mud puddles up there after a lot of rain. I might take my friends up there just to check it out, but I'm putting my DS wheels back on right now, and removing the wheels with the knobbies on them for this ride so I'm not gonna want to get too dirty...
