We see our animals running free all over Wyoming and it's not all that surprising to see a horse or goat or sheep while you're driving down the road. Apparently it's a little less common in other places like Pennsylvania.
Never let anyone tell you that you can't do anything. Obviously, this baby grizzly lives his life that way. He saw a bunch of elk and decided that one would make a nice little snack. If he could catch one of course.
