Was this one of your Moultrie units? If it was, my buddy and I used an idea from my Cuddeback to make our Moultries harder to steal. We drilled a hole through the back of the unit and glue a large washer around it, then we simple screw the unit into the tree. We still wrap a chain around the unit and lock it up but the way we see it is, if these idiots cut the chain/locks and try pulling the camera off the tree and it won't budge, they will probablly either give up or smash the unit, and if they smash it then we will have their pictures.
