So let's review....
1) Can't come after dark to a campground because we might shine our headlights on someones RV/campsite, make too much noise with our tow vehicles, make too much noise setting-up, etc.
2) Can't sleep in a parking lot because we're being cheap, free loaders taking money away from campgrounds.
I guess the rule is we must all only drive after sunrise and be in a campground before sunset.
But we're not allowed in campgrounds since we travel with too many dogs that might pee on the grass killing it off where someone might want to walk barefoot or someone might have to see them poop.:S
