Just got back from Moab, UT. last night, we road trails friday sat. and sun. and that place has some of the most gnary trails I have ever been on. Yesturday they had a down hill race on Porcupine rim so my buddies and I went and road the trail early in the morning before the race. This downhill is 14 miles of "holy shit" and on some parts you are riding on the edge of a 1000 ft cliff!!! (guess thats where "rim" comes from). I've been riding mostly cross country and some all mountain but downhill is great! I highly recommend going to Moab and riding Porcupine rim you wont be disapointed, not one bit.
