If you had a stand that you did not notice right away then you may not get out to your property that frequently. My point is this.

If someone is local and has put up a stand and you are not local but only visit the land several times per year. Then if you take the stand and make a huge deal out of the matter, the local a##whole can do damage to your property if he is nasty.

We own land like this and are careful.

My thought is to turn it over to the local game warden and leave a note on the tree that you have done so.
