Before I got my own place, I had people who were placing trailcams and stands on the land I had permission to hunt. When I spoke to the landowner about it, he told me not to do anything because he was afraid whoever was trespassing would damage his equipment (he did not live on the land). It frustrated the crap out of me and I just did things like pee in front of his stand and trailcams. There is a good chance you WILL run into situations like this if you don't own your own and thought it might be nice to get some creativity going where you don't do anything that will be too confrontational.
