STOCKTON — If the first day is any indication, the San Joaquin County Fair could have a good four-day run.

That’s according to Krista McCoon, who is the fair’s administrative assistant.

She took notice of the long line of people forming at the entrance of the fairground gates at about 1:15 p.m. on Thursday.

The gates opened at 2 o’clock.

What’s more, McCoon said all of the available vendor spaces were gobbled up beforehand.

“Celebrating County Cultures” is this year’s theme, with a number of exhibitors joining in the fun with interactive displays.

“Realizing that everyone defines culture differently, whether it’s your heritage or the culture of your organization, everyone is encouraged to participate,” said fair organizers.

Most of the action was along Brass Ring Amusements’  Midway of Fun featuring thrill rides such as Drop Zone, Century Wheel, Dizzy Dragon and Angry Birds, to name a few.

A variety of food and refreshment vendors along with games and prizes were a stone’s throw away.

Tommy Gutierrez, 61, of Stockton along with his wife found their way to one of their favorite food vendors prior to catching the live entertainment on the Main Stage.

McCoon raved about the promising concert lineup.

Gutierrez, for one, was hoping to hang out long enough to catch Uptown Funk: A Bruno Mars Tribute. He and his wife were already geared up for the Band Fresh, a Latin R&B group from Los Angeles and the opening act.

Tonight is a Country lineup featuring Jackson Michelson (6 p.m.) and Jerrod Niemann (8 p.m.).

Saturday is an evening of power soul and rock kicking off with Chains Required from Sonora (6 p.m.) followed by the Funk / R&B sounds of The Dazz Band (8 p.m.).

Latin singer Gerardo Ortiz closes out the fair with a Sunday performance.
