There's bear hunting...and then there's bear huntin. What I mean is that not all bear are alike. The black bear of the Eastern side of N.America is generally considered to be of a different temperment/nature than the Brown/Kodiac/Grizzly of the Western side.
I don't have experience in hunting those but have bowhunted Black Bear for a number of years;both on stand and on the ground. To consider all bear to have the same personality does them a great disservice and places you(the hunter)in a poorer perspective relative to your own safety.
I've had a couple "interresting" experiences with black bear, having a 400+pounder within about 8feet of me while in a ground blind...and another with a roughly 300pounder interrested in getting into my treestand.(while I was occupying it!)
I guess you can figure out that everything went ok for me. If your interrested, I didn't take a shot at either bear. In my mind I didn't have the proper angle to assure the best possible chance for a kill.
I do carry a "mini fire hydrant" of pepper spray.It's about 8-9" long and about 1 1/2" wide on me and accessable. I also have a very hi intensity flashlight that I keep as well...No such thing as firearm backup while bowhunting where I go in Quebec. Your pretty much on your own once you're in the bush and remain so usually until 10-11:00pm or so.
Something to remember about bears that persue a hunter in the dark hours...their intent is to eat you(most probably). I got that lovely piece of info from a Canadian "Bear Info/Safety" video that discussed the "proper" human reaction to various kind of bears and bear behavior.
Anyway I surly enjoy bear huntin but it is something that ya pretty much know in short order whether ya like or not. Good Huntin. TomL
