I generally camp at state parks and like the sites that are secluded. I bring my dog with me and he has no issues with making his presence known if someone enters our site. The only time I had an issue with people walking through my site was at a christian music festival without my dog. I was at the last site on a dead end and people from the loop behind us would walk through my site because it was easier to get to the restroom. At first I was annoyed but then decided to have fun with it and like CampingFamily1, I started to engage with anyone who walked through. Oddly enough, the amount of traffic was reduced once people realized that they would have to be subject to questioning and conversation. I realize that for some people it may be their first time camping. However, one would hope that common sense and well, good manners might lead a person to at least ask permission to enter someone else's site. Call me old fashion but whether they believe it or not, the rule if you don't want someone doing it to you then don't do it to others applies to camping as well.
