The fair closes Sunday night.
But there is still a few days to see Solano's 2012 exhibit, which also won Gold Award and Craftsmanship Award honors this year.
The exhibit features a walk-through barn and a farm stand displaying Solano-grown fruits and vegetables.
"The exhibit integrates a learning environment with whimsical characters, abundant memorabilia, twinkling lights and animated displays," county officials said at the start of the fair.
The carnival midway stays open until 11 p.m. Thursday and until midnight Friday, Saturday and Sunday.
Tickets cost $12 for adults through age 61 and $10 for 62 and older. Children from age 5 to age 12 pay $8, and kids under 5 get admitted free. Parking costs an additional $10.
The special kids park operates until 11 p.m. on Thursday and until midnight on Friday, Saturday and Sunday.
Final weekend performers include hypnotist Suzie Haner and band Set in Stone on Thursday,and the Blackhearts on Friday, a Sting tribute band on Saturday, and Ezequiel Pena and Bandas Machos on Sunday.
The state fair wraps up just days before the start of the Solano County Fair, which runs Aug. 1-5 at the county fairgrounds in Vallejo.
