I posted in the general forum, but not sure if you guys get around to it much.

Essentially, my buddy is trying to build an offroad trail database using a wiki and Google Earth 3D flyovers. He wants to have a central location instead of tidbits of info spread out all over the net. If you'd like to contribute and help us out, you can check his site out here: www.dirtopia.com

Since he lives in Southern Cal, you will see mostly Southern Cal info, but his goal is to get every trail in the US(ambitious, I know).
