Many campgrounds in the eastern US (public ones) will not allow that. And that includes "dispersed" campsites (ie: the "wide spot" in the road kind).[/quote]
Didn't really give it much thought really. However, I would be doing most of my camping at state parks. They should have facilities there, if not, I could rough it for a day or two. After all, it is camping
However, for future reference, I could figure something else out like a trailer I could pull that is designated as a bathroom. I could take it if its needed, or leave it at home if the place I'm going has facilities.
