The event is the "Oh! - Limpics". We can't use your suggestion, intriguing as it is, because entire cars are not part of the event. It is a NON-driving team competition.
It requires a 3 member, mixed gender team and consists of 5 segments or pentathlon (Oh, gosh - maybe we can get Chrysler sponsorship!). We can't be sure of what the exact events will be until we get to Big Sky and see what facilities are available for staging it. Most likely it will include a spare tire slalom, fan belt horseshoes, piston croquet and two more of several possible challenges.
This event allows attendees who are without cars a chance to join in the action and teams from the different clubs to vie for bragging rights.
The Oh! - Limpics will be presented by the Sunbeam Owners Group of San Diego.
