I feel your pain Coalcracker. I had 2 cameras stolen end of the 07' season. It was in the last wk, and I moved 2 my cameras to a section of apple tree's the deer were hitting. I got lazy, and didn't secure them like I usually do. There was 6" snow on the ground, figuring noone would trespass when I could follow their prints. Well this low life trepassed, shot a deer, and dragged it out right by my trail cameras. I was thinking great I'll have him on camera! Instead I found he took my trail cameras with him to. To add a little kick in the butt he dragged the deer within 5ft of my camp.
So now I lock them all with chain/cable & padlock. Plus I put a few several feet up in tree's to catch any trespassers.
