One time we set up camp in an area that looked like it was overun by some sort of militia. ATVs crawling through the campground slowly with rifles secured to the front end. I manuevered to a safe secluded area, but was close to the ATV trail they were using. I set up my tent next to the trail and built my fire pit in the middle of the trail. Needless to say, they stayed cleared of my area and went around. The trail wasn't a marked trail, just a new one that this group was using. No confrontations. No problems. The campground only had three campers and the ATVers I assume didn't want to run over my fire pit.
P.S. I didn't have any piano wire on me, but I did have a shovel.
