> they have made that illegal

We have the Food Freedom Act in Wyoming [1]. It technically requires meat be sold "for future delivery provided that the processing of the animals is done by the purchaser or by a Wyoming or federally licensed processing facility."

But in my experience, ranchers are liberal with how they define me "processing" my meat. (In one case, he pointed out the bits of silver skin he hadn't trimmed. So I "processed" those off at home.)
