Looks like the bureau of land management, blinked.
Not sure someone should not pay grazing fees, but also not sure why the feds own 99% of Nevada in the first place. I say, open up all that public land to settler's, like it once was. If this guy has been feeding his cattle the weeds and scrub brush on that property for 100 years, maybe he is owed 80 years of refunds, and a deed to the property.
I am not big on something for nothing, welfare, hand outs, but this guy has a working ranch, for a century, and I would tend to trust him, over the feds.
