Organized by Biker Down Alerts, volunteers washed cars and bikes in support of Breann Creer and her family.
Creer died Aug. 27 while riding on the back of a motorcycle that collided with a semi truck in Rancho Cucamonga.
Saturday's car wash also featured a raffle. Organizers hope to raise over $5,000 from the event. A pizza party is planned for later this week.
Fundraising donations to the Creer family can be made to:
Wells Fargo Bank, account no. 3344876523.
