There is a woman out in western Montana that makes a dang good living off bears like your buddy. She has a large pack of well trained bear dogs, a high powered paintball gun, and some real cojones. She is hired to deal with people's problem bears, including griz.
Between her dogs and the paintball gun, she uses negative reinforcement to teach the bears that dumpster diving and other behaviors lead to being chased all over creation all the while getting stung in the butt. Apparently she is also quite a healthy and fit cross country runner because she does a fair job keeping up with the dogs. From what I understand about bears, the one thing they are not fond of is unnecessary exercise!
Grab a full quiver of blunt fluflus and your running shoes!
