[Big Papa Goat]

Jesus, its not a matter of having to eat your own arms, its a matter of buying and bringing a ten dollar lifejacket that could easily save your life and perhaps more importantly, save other life savers from having to save your life rather then the people that originally needed to be saved.
It's not like they have to bring fire extingushers or little reflective strips on their clothes, its floatation devices in a place that is filled with water.
