Damn Utah has some crazy MTB shit, check out these spine runs. It looks like if you don't get the landing right on a couple of those drops your off the side of the cliff. Around 2:55 it really starts to get spicy.
Also in case anyone doesn't realize, its hot as balls out so be careful out there. I went for a quick and easy 15 minute bike ride yesterday around 7PM and it was still so hot and humid I could barley breathe. The trails don't seem to be liking the lack of rain either, freakin Mojavi Desert status out there, but I tuned up the tree jump lip, and Adam scroed some sweet tarp so hopefully that keeps things moist.
