I found this video of a 4x4 hill climbing http://www.youtube.com/watch?v=McBznI6h2jA . I was talking to a guy who came in to my work and he hill climbs its timed u get points for the faster u get up the hill and u lose points for falling back down. I have a 45 deg slope/dam wall that would rock when its wet as i said B4 im going to try it as soon as my ST1 is running again
