Warren,
Great pictures. Maybe you will be lucky and get some nice weather this time. Or not! Loved the Old Dirt Road. As for the drive, you can do that here on some of these trails the forestry has cut up the canyon walls for fire access, except they haven't kept them up and most them are only accessible now by motorcycle or a 4 wheeler and even they you have to push them across places the earthquakes have caused to break.
