The biggest event of the 2019 Delta County Fair is the Demolition Derby. The action starts at 7 p.m. Saturday, Aug. 10. Drivers are 18 and older and cars, modified to specifications, are generally older models from the 1970s -- the Ford LTDs and Crown Victorias, Chevy Impalas, Cadillacs and other models with heavy-duty, solid-steel frames. Who will have the best car this year to make it to the finals and outlast all other cars? Arrive early, as stadium seats fill fast. No need to wait in line, as tickets are available at deltacountyfair.com.
