I know you have probably wondered about it all your life, so let me just say...
There is right around 80 pounds of ground meat in a small elk. After the good steaks, the stew meat, the roasts and some jerky meat, you end up with about 80 pounds of ground.
Eighty. 8 - 0. From a small elk.
So. Got any good burger recipes? After nearly 30 years of this, I'm out of ideas. :-)
