I had a similar situation with a friend who had leased a couple of sections around Buras for duck hunting. The locals would hunt the blinds during the week days, we would hunt the weekends. The lease holders that complained usually had a bonfire held at their hunting camp that they were not invited to

. My friend accepted that the locals felt they had a God given right to hunt in 'their back yard'; he called it the Buras Duck Tax

.
It sucks but unless you have 'eyes on the property' from another local, you may have to accept it. A conversation with the Sheriff would not hurt...unless it is his BIL that you caught on camera!
