Sorry for the over post, but I have to get this out there: DO NOT EVER USE LOOM FOR A MOTOCROSS TRACK. EVER! It doesn't compress enough to make jumps or berms... I made a jump today with a ten foot gap, not even big, and I hit it and the front tire sank down into the take off ramp and went right through (literally, I have tire marks to prove it) the receiving ramp... That was after it was compacted by weight of machines... Total busted idea, had fun hitting the jump and making it and stuff, but I think I'm going to stick with all ready made tracks. Oh well, maybe I can have a nice front lawn this year
