Mine is not a stand off, but a black bear attacked my deer feeder last night, tearing the metal ring and lid off of it.
Feeder was about 15 feet up in the tree, but ol blacky climbed the tree and reached out and got a grip on the rope. Spilled about 50 pounds out of it. I put the lid back on and hoisted the feeder back up hoping he or she does not come back. That feeder is strictly for the squirrels, deer and turkeys. I do not hunt around it.
