Walkers

I'm guessing since it was Watkins glen the problem was you were dealing with people who don't normally camp or understand campground etiquette. I see this phenomenon on holiday weekends all the time. I generally am pretty patient but when they get to the point of getting under my awning or touching my stuff, I take issue and will say something. Usually my first move is to rearrange camp to block the path a bit.

That said, I really like the crime scene tape, chalk outline idea. My rd would love to outline one of us. What fun She would have doing that.
