Some enterprising Montanan should buy an acre of Montana land, break it up into postage sized parcels, then sell one of the postage sized parcels for a nominal amount; plus obtain a Montana post office box. The purchaser of such a parcel and box by visiting the parcel from time to time and picking up his junk mail could then claim Montana citizenship and register his car. Anything to deny the blood suckers their precious dollars with which to buy votes.
Someone was selling 1 square inch lots somewhere. Deeded, taxed, and all. Amusing story, look it up.
