I saw this tonight, and I gotta say, "I Like It". I had one of those "Why didn't I think of that?" moments.
A fanatical bowhunter from Alaska commonly comes in contact with Black and Brown Bears. Bears are notorious for putting a hurtin' on game cameras. Some security boxes even have a hard time standing up to them. So this guy developed a steel game camera box that is lag-bolted to the tree, and covered with nasty, sharp spikes.
I hop this guy patented the idea. Check out his bear proof security box.
