I've got a dozen neighbors I could go to, pay cash for a cow, pay cash to the local processor, and have a freezer full of evil meat that the gov knows nothing about.
Are you sure? Remember, when the mad cow disease thing broke out several years ago, the U.S. gummint was able to trace a single cow from somewhere in Canada to a barn somewhere in the United States.
(But we can't find 11,000,000 -- or is it 13,000,000? -- illegal alien humans.)
