I'm not sure about Oregon and Nor Cal but as far as SoCal there's Pismo, Glamis, Octillo for dunes and sand...Theres also Joshua Tree...Then theres Gorman off road park off the 5 freeway I think it is...Not sure on the exact location of that one...I think there is a map on this site somewhere that has a list of all the offroad parks in CA...Hope this helps ya atleast a little bit <img src="/forums/images/graemlins/kewl.gif" alt="" />
