I utilize every edible part of the animal including all the meat, the heart, the liver and the tongue. I have always butchered my own meat which means I cut, trim, vacuum pack it and freeze it. My family hasn't bought store bought meat since 1986. A buzzard would starve off a skeleton after I'm done with it.
Frankly, I don't know about the rest of you, but for a new guy to come on the forum and even ask if a hunter just takes the head and leaves the rest to rot kind of PI$$ES me off! No hunter would do that. A poacher would but a hunter would not and if this guy doesn't understand the difference then he is utterly clueless!
