(Note: Some states offer a one-day "moving permit" and/or a "trip permit" for multiple days, for otherwise unregistered vehicles. These permits, conceivably, could be used to drive a vehicle over a weekend, to a car show! Check your local DMV/MVD or AAA for cost, availability, and additional requirements).
