Im genuinely curious--why not?
I didn’t feel any need to. Mostly because I camped in places where there few people around, and there was no public access. The few people I did camp around didn’t look like they needed or wanted to steal anything. I spent two nights at a state park campground that was nearly empty, and my site was up a little hill off the campground road and in the trees. Doubt anyone could even see me from the road.
