An old Hank song comes to mind. Family Tradition. It all started hundreds of years ago back in the old country(Germany). You see, my ancestors were the noted hunters of the community and my last name literally means hunter. I have written history of one of my ancestors who fought in the first battle of the Revolutionary War that says he was an exceptional marksman capable of taking down even the fastest game.
I've lived all of my life not too far from that battleground and I guess you can say it's just in my blood.
I have no specific reason. It's just what I've always done to quell my insatiable hunger for animal flesh.
