There is a saying in the "brain tan" arena, that every animal (except the buffalo and most PETA members) has enough brains in its head to tan it's own hide. Mother nature design it that way, so that any animal is a complete package for the hunter. Flesh to eat, bones and sinew for tools, hides and brains for shelter and clothing. One just needs to know how to extract all the possiblities.
Nature is a magical thing, too bad allot of folks have forgoten or lost many of her secrets.
