Celebrating 20 years of action, the Spring California Truck Jam was held at the beautiful Verizon Amphitheater at Hidden Valley Park in Irvine, California, on Sunday, May 6, 2007. Attracting hundreds of custom and classic show trucks and SUVs, the variety ranged from cover trucks to under construction, full size trucks and SUVs to mini trucks, and ridiculously lifted trucks to trucks body dropped to the doors. Many enthusiasts and locals spent the day checking out the Burnout Contest, Air Hop Contest, Bikini Contest, and the Shocker Monster Truck Crush, while others relaxed in shade provided by the trees at this perfect Orange County venue for a custom truck show.
