What i think is happening is someone is driving by and letting another person out so there is no vehicle. The only way into the property is from the front so they see my truck pull in and get out well before I can get to the stand. They are probably not wearing orange either. The stands have sides on them and a door, so I at least took the chairs out of them so that the only way to hunt them would be to sit on your knees. The next gun season here starts Thanksgiving so I' ll have to put my chairs back in the night before I hunt.
