We put up almost 25 signs yesterday hoping i don't get any trespassers this year. I bought a variety of color signs (3) and cut boards for some and painted some florescent colors, put them up high so they are seen and can't be reached. Had to go over a line to get them on our trees and there were 2 cameras and i held the signs so they could see what were doing.
I have been lucky my cameras have not been touched and was surprised this guy had his locked and cabled, too bad people can't be trusted not to touch what is no theirs
