All of our race pods are on wheels, so they can be removed from the trailer and setup indoors. Indoor events require a LOT of extra setup time and work to un-install and re-install the simulators to the trailer itself. Often a simple 3 hour event, becomes a 3 Day event for us. Because of this, we charge twice as much for indoor events than we do for events that make use of our trailer. Events that take place early in the day, may need to be setup the day/night before.
