Apparently you haven’t visited much of the back country recently. To get a permit some places you must take the toilet seat and bucket and bags. I can’t imagine packing around a 5 gallon bucket and seat but it is regulation.
I saw them at the Denali Park HQ for climbers and again in far off Texas on the Rio Grande.
No, I just usually avoid permitted campgrounds. I like going back into wilderness areas where I don’t have a lot of company.
