By the time one reaches my age they have seen many things. Like the man in Tenn in the middle of the road feeding a cracker to a full grown bear. That bear swatted his hand so hard and fast it wrapped around his neck. The bear only wanted the cracker not to harm the man. Next a mother and 2 children 8-9 years old in Cades Cove in pursuit of a mother bear and her two cubs in an open field. I don't know what she planned to do if they caught them. And lastly a 11-12 year old kid at Grand Canyon climbed over rock wall fence out on ledge. Several hundred feet fall was possible.
