Batter fried onion rings

Yesterday I drove past Pleasanton CA over 80 east toward Davis.  I try to leave mid-morning when the commute traffic has calmed down, but there is still a hilly part where traffic is a bit slow.  I saw a few motor homes in the slow lane, then a SHAVE ICE vendor being pulled by a truck.  Another SHAVE ICE truck being pulled by a motor home.   A HOT DOG truck was ahead of that.   When I passed the Batter Fried Onion Rings truck, I realized that I had just passed the fair grounds in Pleasanton and the fair was over yesterday.
