a year before my buddy sent a rubber broadhead off this guys noggin for 3 nights in a row. Bear season was closed so he couldn't shoot him and he never laid eyes on a deer when this guy was around. He has lush food plots in this more open farm-like property and so when a bear takes up residence he may not leave for awhile even when he gets a non-lethal "deterrent". It has messed up deer hunts for us however so I wouldn't say they aren't an issue other than to fawns.
