A couple of thoughts from a farmer’s perspective…

In addition to refusing to pay the grazing/leasing fee, Mr. Bundy also:
1) Allows his cattle to foul springs and other water sources/waterways.
2) Allows his cattle to trample and seriously damage riparian areas.

As a farmer myself, I am forbidden by federal law, from allowing my own livestock to do such things on my PRIVATELY OWNED property.
Those federal regulations are in place precisely because of irresponsible people like Mr. Bundy.
Mr. Bundy apparently has no problem with shitting in his own yard, and everyone else’s as well.
