nah, Columbia Point is open and you regularly see trucks, motorcycles, and quads out there on the weekend. there is a fairly large set of dunes out by road 100 that were closed down cause 4wheelers would stray off the path and go over farmers land ruining that part of their crop. really sucks cause i never had a chance to try it out with my truck. for all you wet-siders, i will try to look into juniper and see if it is a overnight thing could work.
