The theme takes the Lewis Carroll classic “Alice's Adventures in Wonderland,'' and mixes in some steampunk and cosplay, organizers said. A Mad DJ Party is scheduled in the theme exhibit at 7 p.m.
An opening ceremony for the fair is scheduled for 3:30 p.m. at the O'Brien Gate, and the public will be let in beginning at 4 p.m. Switchfoot will perform on the Grandstand Stage beginning at 7:30 p.m.
The fair will run 26 days through July 4. It will be closed Mondays -- except for closing day -- and the first two Tuesdays. General admission is $16, while a $26 pass allows admission each day.
Organizers urge the public to use public transit. A valid North County Transit District, Amtrak or Compass pass allows for a free shuttle ride from the Solana Beach train station.
