SONOMA, Calif. - John Lasseter, a two-time Academy Award winning director, will be a participant in the Holiday Sobriety Challenge on Thursday, December 14, at Sears Point Raceway. Lasseter, who is known best for his work on "Toy Story," "Toy Story 2" and "A Bug's Life," is a resident of Sonoma.

The Challenge will feature a controlled wine and beer tasting experiment that will graphically illustrate how alcohol consumption affects driving performance. The event runs from 11 a.m.-2 p.m. (CA Time).

The participants who will take part in the experiment will each be served 1 to 3 glasses of wine or beer upon arrival. They will then be taken through a series of field sobriety tests by CHP officers, including a Breathalyzer analysis, before being asked to drive around a pre-determined course at speed. They will be joined in the cars by racing instructors from the Jim Russell Racing Drivers School for safety reasons.

The Challenge is sponsored by the CHP, Jim Russell Racing Driver's School and Sears Point Raceway.
