I keep meaning to grift the SovCits, with new and exciting producta. For example, license plates with yellow fringe on them to indicate they are actually seagoing vessels portaging overland between navigable waters. You just have to drive them to a boat ramp and let their wheels touch the water from time to time, to make them subject to maritime law. This allows you to use them even for commerce without needing to register them with the DMV.
