ran it a gain a couple of times last night, hit a rock going pretty good with about 15psi in the front tires and knocked the drivers side one flat. This happened where Saw Mill (I think) turns off to the left, continued to run on the flat (figured wtf, it might happen in the race) 8:38 to the road with the flat. No tire damage, beat the bent part of the inner bead back in, aired up the tires and ran again. A clean run the 2nd time 7:50 stopping for mud puddles. There is going to be major carnage I predict.
P.S. Maxxis Tires rule!!!
