West Coast Thunder

West Coast Thunder is a tax-exempt nonprofit organization based at 7688 Indiana Avenue in Riverside, California, the same address as Riverside Harley-Davidson. Each Memorial Day, the organization runs the West Coast Thunder Memorial Day Motorcycle Ride, described as the largest Memorial Day motorcycle ride west of the Mississippi, drawing thousands of riders who fill multiple lanes of Indiana Avenue for the procession. Proceeds from West Coast Thunder events go to the Riverside National Cemetery Support Committee through the West Coast Thunder Foundation, and the organization has been a major funding contributor to Riverside National Cemetery, the largest cemetery in the U.S. National Cemetery System, since 2000.
