Thanks everyone. I was a little worried about how the photos would come out. I had to order a new lens for my Sony Nex, so I carried our old Nikon D80 on this hike.
I was kinda surprised by how bad the road was. I don't think a 4wd is necessary, but the washboarding is really bad. My buddy drove his Honda CRV and it had a new noise in the front end by the time we were off the dirt road. We did see small cars up there, incuding a suzuiki econo-box.
