Car Pool to Races: Why?
Obviously, if you and two others share a car, it uses less gas and less $$
Just as obvious; less gas used, a smaller carbon footprint
Ease Parking Congestion
Fewer cars in the parking areas make for happier local residents, less impact on parks, schols and private property, and easier permit processes for the organizers
Lessen impact of Injuries
In the event of a crash and injury, an uninjured driver can drive for an injured one. It is difficult for the organizers to ferry several single driver's cars around each weekend, coordinating the rider's bicycle and other equipment. It is also much safer to not have a rider with an injury drive him or herself home. Besides, wouldn't you rather have a friend help you out and drive you home? (and don't think this won't happen to you!)
You could also consider taking the train; Amtrak, Caltrain and BART go to many of our race venues, including Merced, Hanford, Madera, Suisun City, Fremont and others.
