Random question for those of you who live/work/vacation in bear country. I'm taking a vacation to the smokies in the middle of next month, and thought of something regarding bears and "bear spray". Is there really much of a difference in "bear spray" and regular OC spray? I have a MK-4 can that was thinking of taking along for the trip; just curious if it would be effective at all in the rare instance I would have to deal with a highly irritated bruin.
