I only stayed in a few youth hostels recently. San Louis Obispo, California and Tuscon, Arizona. I try to stay to the National Park campgrounds... they cost a little bit, but they are worth it to check into because they have regular law enforcement patrols. Second choice would be US Forest Service Campgrounds... then State Parks. KOA will work in a pinch, also, but are mostly RV oriented. Good luck!
