Bundy can take the newborn calves and sell them to his kids for a dollar a head. They put their brand on them and in a year sell them at a livestock auction. The BLM might know whats going on but there’s not a damn thing they can do about it.
And what does he live on? Unless he enters into a barter existence then he's got to sell something. And even if he bartered his cows for goods and services the feds will to after whoever he traded the cow to, since it's legally their cow to begin with. Bundy may think he's won but it's just starting. If he still has his ranch once the dust settles I'll be very surprised.
