hunting for animals that can kill you is supposedly the most adrenalin-rushing activity that exists. kind of like getting a couple of buddies together to try & spring a friend from jail, i guess... hunting lions from horseback with spears was a very popular sport amongst monied young men from jolly olde England back in the day...more than a few graves in Africa resulted from activities like this. or hunting Cape buffalo with black powder rifles, which may or may not go off when you want them to.
