Sean Baumstark (27, FA) was a huge contributor to Ride Ataxia II. Because of his experience with Ride Ataxia and the huge support he has received from friends, family and coworkers he has started an effort to push the limits of one's personal physical ability. The effort is called DE:TERMINENCE and it launched on September 28, 2008 at the Autism Speaks fundraiser at the UC Davis M.I.N.D. Institute here in Sacramento, CA.
