A few weeks ago I spent a weekend at nice private campground nearby. Been there before, no issues. My site was in a transient loopmjust opposite the bathhouse. This particular weekend there was a tent group of about 30 staying in the same loop. It was obvious they were rookies. Everyone of them must have walked through my site at least 10 times (300 total) to access the bathroom. They could have gone around but was obvious they didn't know any better. I thought about saying something to the campground office but then thought that it was better to just let it be. Yes it we as my space but why create animosity over something so trivial.
I will say though that is was rather entertaining watching them jump every time my protective 85 lb leashed lab growled and became aggressive every time one of them passed through.:-)
I say live and let live as long as it isn't causing me or my family harm.
