Sweet, Raptor and gun talk, I love it! The Terrain is mostly desert, but can my rocky. But it's pretty wide open, not like the jeep trails in the Sierras/Rubicon, not to say there aren't trails with rocks for jeeps and those types of rigs.
Nv Guy will be able to fill you in more though, but check out this site and the course they had this year, I think that course will be our next meet/run.
Vorra USA 500
