When we were doing the campground thing, i could see both sides of the fence clearly. The rules are necessary. No doubt. Common courtesy is of the utmost importance so everyone can enjoy their stay. There are however, those campers who mean no harm and may not realize they are upsetting their neighbors. Along those same lines, there are those who don't give a darn. That's why the rules are necessary.
Then there are those CG's that have the seasonal residents who have taken on the position of being the CG Police. And they take that position a little too serious. Some CG's have their own enforcement patrols. We got blackballed from a CG once in northern MI for sitting around the campfire a little too long. Only about 6 of us adults (all the kids in bed) having a nice quiet conversation and relaxing. We were very conscious of not disturbing any of the our neighbors. No complants from them. Nothing was said by anyone and we all went in to hit the hay by 11:30 PM.
The next day was the day to move on. Also the day we found out we were blackballed upon checkout. When inquiring to what the heck we did that was so terrible to get us banned, he said we were up almost 30 minutes past curfew and fires out. OOPS! An oversight and I explained that we made sure we were all quiet as church mice. Made no difference. Apparently, "Ranger Rick" was patrolling the park and spotted us. No complants were made. But, we broke the rules and we were all never to come back. REALLY? There is more to the story but would make the post way too long.
A lot has been said on park etiquette. Search it in the forum. Some parks are fine with normal activity, some aren't and are a lot stricter. Some parks are for fun, some are like little concentration camps. Some campers like little concentration camps, some don't. There are a whole bunch of CG's in the middle. You just have to do the research or find them on your own. It's a crap shoot. The number of rules, how they are enforced, how those rules are displayed, etc., are all part of the game.
