Silent Disco at the State Fair

State Fair patrons can feel alone in a crowded room in one more sense this year: at the Silent Disco. Each day at this fair exhibition, visitors receive wireless headphones that broadcast music, making for a hundred private concerts and one communal, crowd-sourced social experiment. Before 5 p.m., the music is kid-friendly—in the evening, anything goes, lyrically. Other fair highlights include a pie-eating contest on July 17, the Best of California Brewfest on July 21, a youth mariachi competition on July 22 and wiener dog races on July 28. Look for discounted-entry Mondays when you donate three nonperishable food items, and State-Fair-food tasting days Wednesdays and Thursdays with $2 samples of grub. 1600 Exposition Boulevard, castatefair.org.
