In WY non-res. hunters can only butcher and bone out a cow if you leave 1 piece of meat with a patch of skin and 1 teat attached. The whole hide with head attached isn't proof enough to show it's a cow. That is, unless you give the local butch the business and then everything can be bone, wrapped and no other proof is needed.

(You're saying some game laws in Wisc. are dumb? Afterall, that is where they wear big blocks of cheese on their heads! You "cheddar headers" you.
