Seems we have a common theme from the comments posted about offending camp site behavior.
We camp mainly on the state park circuit so I cannot give a reference to non state park camps. However we do get some folks with less then stellar activities at the camp site. Not many but we are not immune to them. We had one last year I thought I was going to have to peal my DW off the ceiling of the camper....
It was now about 11:30pm and the campsite next to us had a corn hole game going on. It's a real big deal here in Ohio. Must be a state past time I think....Thunk, thunk, thunk, thunk goes the bean bags followed by a "yeh" at about 90 decibels ... which is really loud... That and the qty 4, 1,000 watt halogen shop lights illuminating half the camping circle.... By midnight the game stopped thank goodness. I was hopping the power cord to the lights would of melted sooner....
Also there is the radio load group that leave it blasting when they are not even at the camp site.....
Then there are the kids who ride their bikes 3 wide right through your camp site and dodge the awning straps, picnic table and camper on the way through.... Followed by the set of parents yak'ing away after them and never even stopped and say hi.... Where do ya think the kids get it from? Cindy really chewed a few out last year. I see she found her tolerance level.
And then to me is the worst, leaving trash on the ground

I have zero tolerance for that one. So I grumble to myself and just go pick it up as I'm not camping in that... nor do I want to leave it for the next person.
The common thing missing is "respect" for your fellow camper, your fellow person and the great place in nature we come on purpose to be in.
I have no issues with folks having a good time, listening to their favorite tunes or coming over to your camp site to pass through, however keeping the respect factor up makes all the difference.
A radio turned down so it can only be heard by the folks right on top of it, stopping the corn hole when it gets dark, saying hello when you enter camp makes all the difference. Heck if someone comes over to your camp site and strikes up a conversion, soon comes an offer to sit down and have a cold one and yak some more.
While we do have some small level of offending behavior in our state parks, the majority of camper folks are a good group of people. And our whole society would be a better place if more folks went camping. Respect starts with the simple things and so does camping.
