If we get to an area where we can't find a camp site but there isn't a Walmart what options do we have? Can you get away with pulling over into a different parking lot or off the side of a road? My concern is at some point getting caught in no mans land where we are driving around at sundown with no place to stay and getting rousted by cops and having to keep moving throughout the night. For instance, if we can't find a camp site in Yellowstone, do we have to drive out of the park at night and what if there isn't a walmart around? Same along the Oregon coast (though I suspect we'd find more walmarts even if we have to go inland). Thanks again for all the help!
