Nature expert Jack Hanna shares a story in which a young grizzly that got a little too close for comfort during a recent hike through Montana's back country. Chatting with 'Early Show' anchor Harry Smith via live video feed, Jack gives us a play-by-play of his close encounter with the curious bear. "The bear's about 25, 30 feet away now, see, and I found out later that it's a male trying to show his umph."

Jack then demonstrates how he got his bear spray ready, "I point it at the bear and I didn't want to have the bear, you know, start squealing or something, making problems, the mother would come back." When the bear got within ten feet, Hanna blasted him in the face. "I didn't sleep much that night, but now I'm getting ready to go back up the same trail on Saturday," Jack explains.
