Lots of bear inflicted insomnia this year. A local fellow here found himself in close proximity to a polar bear, which when it approached him he dissuaded by swatting it in the face with his dog leash! When the bear backed off, he started to back away as he frantically searched for the cell phone to call the DNR guy. Sure enough, while backing away, he stumbled and fell on his back, which immediately brought the bear back to him. A moment later the bear patrol guys were on the scene and cracker shelled the bear away.
Now as bad as I think bear spray is as a primary line of defense, it beats a leash any day. As for me I'll stick to packing a gun.
