I haven't hunted those Wyoming units but I live and hunt in N.W. Montana and for the last 8 years in a row I run into atleast one.Don't hunt alone anymore for that specific reason call it being a wuss or whatever. The return to a kill in G-Bear country is risky that you may have one on it. We hunt with a pack on our backs at all times so if at all possible don't have to leave an animal in the woods all night. 4 years ago here 2 guys were returning to a kill that was left all night and a G-bear attacked them got one on the ground and his buddy shot it, later he said he probably would have been dead if he wasn;t there to shoot it. Not trying to scare you it's just things to consider when hunting in G-Bear country.
