Another tourist was butted by a bison in the park. The group got within 10 feet of this wild animal; STUPID. Are these adults brain dead? We need to start putting billboards up before entering the park showing injuries from wild animal attacks; just like we did for the meth users. It still wouldn't stop all of them, but it might help some. A large fine would also help people who get too close to animals. You get nailed for no fishing license, so you ought to be fined for no brains.
