What I’ve heard of Grizzlies, they will chop you up for the fun of it. Almost as bad as Polar Bears. Black bears are mostly afraid of humans, dogs and loud noises but when it’s a momma and her cubs, all bets are off. I saw all the elk in Estes Park, wouldn’t want to mess with those or moose. They’ll ruin your day. Don’t have either in WV to be concerned about. Just flocks of wild turkeys that might get rowdy if you catch them in a bad mood.
Grizzlies don’t do anything for fun. They defend themselves and they hunt for food. Coming out of winter sleep they are generally hungry and cranky. If you startle one they defend themselves and retreat most times. It’s the defend themselves portion that gets people tore all to hell. Throw a cub in the mix? The brakes are off. My main experience is fall elk hunting. I don’t hike unless it’s for meat. The spring hiking cross threads folks with cranky bears. Nothing new here. Yellowstone ain’t a petting zoo. The country, the weather, the wild life, and the water can and will kill you if you’re careless or just plain stupid. I wouldn’t trade this country for anything. But I damn sure respect what it can do. Be safe
