Bull, I even tried to reason this out in my mind, and the only thing I can come up with is they (those Park & Recreation Areas) won't have "Restroom" services...
Obviously they have never heard of "Porta-Potty's"
This really puts the screws to my summer plans with the grand kids and my wife for some fishing, boating, and camping... Guess I won't have to buy a Park Sticker.
