Review for Sonoma County Fairgrounds Review For Sonoma County Fairgrounds Google User Aug 14 '11 at 5:50 The rides were too expensive. We (family of four) went through the security check point, bought 45 ride tickets ($35), we all went on 2 rides, and then the kids went on a bee ride. This all took 20 minutes and we had 3 tickets left. The food was a little expensive too, but good. We spent $90 on the 45 ride tickets, dinner (for two cause the kids weren't hungry), and non-alcohol drinks. We went to the destruction derby, we had a blast. The entry tickets and destruction derby tickets were addition to the $90. View full site to comment or like
