There are only five days left to experience the final chapter of Once Upon a Fair, the San Diego County Fair’s storybook theme. The fair, which is closed Mondays and Tuesdays, returns Wednesday at 11 a.m. and ends Sunday at 11 p.m.

Fairgoers will recognize a lot of the returning rides, food vendors and agricultural experiences, but some of what they’ll find will not return next year.

“The fair is always a mix of old and new,” said fair spokesperson Tristan Hallman. “It’s the traditions that people come for every single year, and then we have the new entertainment, the acts that haven’t been here for years or never at all.”

Hallman noted the fair’s 20,000-square-foot custom-built theme exhibit, which includes learning experiences, photo opportunities and hands-on activities centered around the joy of reading. He also touted the fair’s recent enhancements to the Great American Petting Farm and food innovations like this year’s winning churro dog.

The final five days will also feature a number of events unique to this week, including Fourth of July celebrations, monster trucks and motorsports, Bluegrass Day, a Black and Brown Festival Showcase and new concert performers.

Here’s some of what San Diegans can expect as the fair comes to a close.

Fourth of July

The San Diego County Fair has planned a number of events to celebrate America’s 250th birthday.

“It’s the Fourth of July at the fair — there’s nothing like it,” said Hallman. “We’ve got a lot of activities that celebrate America, so it’s going to be be action-packed.”

Throughout the week, military artist Joe Pisano invites fair guests to watch him create Lady Liberty, a 20-foot replica of the Statue of Liberty made out of around 80,000 drywall screws. Visitors can write letters to the future, which will be preserved in a time capsule inside the statue’s torch until America’s 300th birthday, 50 years from now.

Thursday, the fair is hosting a quilt block contest with an American Heritage theme. Participants can create their quilt blocks in advance, which should be 10.5 square inches and inspired by heritage, culture and family history of home.

On the Fourth of July, the fair is holding a parade at 2 p.m. The parade’s Grand Marshall will be Dr. Seuss’s Cat in the Hat and there will be performances by Marine Band San Diego and the Euphoria Brass Band. Marine Band San Diego will also perform on the Grandstand stage at 7:30 p.m., followed by the fair’s annual fireworks show at 9 p.m.

Monster trucks and motorsports

From Wednesday to Friday, fair attendees will hear the revving of engines as they watch muscle machines roar, climb and fly around the Del Mar Arena. Events will include mini monster trucks, junior mini sprints, junior outlaw, lawn mower racing and monster truck glow shows.

Concerts

The final week of the fair will kick off with three headliners on Wednesday. Pop band AJR will play on the Corona Grandstand Stage, comedian Andrew Dice Clay will perform at The Sound and San Diego pop musician Matthew Phillips will play on the Chevrolet Paddock Stage.

Other concerts slated throughout the week include KISS tribute band Kissed Alive on Thursday and country singer Warren Zeiders and famed ’70s and ’80s rock band Jefferson Starship on Friday. Saturday, EDM collective Brownies & Lemonade will perform for Fourth of July. Mexican norteño-sax band Conjunto Primavera and Latin beats and rock disc jockey Domingueando DJ, also known as Royal Zeven, will close out the fair on Sunday.

Final day events

Sunday, the fair will hold a Bluegrass Day with a variety of performances at the Michelob ULTRA Avenue Stage between 11 a.m. and 5 p.m. In addition to the style of old-time mountain music, the event will feature square dance fiddling, blues, gospel music, jazz and pop music. Performances will include improvisation, a band scramble and an awards show. Bluegrass Day will involve musicians of all ages, kicking off with a youth performance.

Also Sunday, fair visitors can attend a Black & Brown Festival Showcase at the Chevrolet Paddock Stage from 2 p.m. to 5 p.m. Presented by local nonprofit Movement BE, it will emphasize live music, dance, spoken word and community.
