PRINCETON — The most unique attraction at the 160th Bureau County Fair in Princeton is the demolition derby, set for 3 p.m. Sunday, Aug. 30, and presented by and sponsored by Spring Valley City Bank, Dakota Street Insurance, Heartland Auto Body and Central Bank.

Demolition derbies always attract more people than any other event at the county fair because its fun for both drivers and spectators. “This is an opportunity to break every traffic law there is and maybe get paid for it.” The object is simple: Two rows of cars line up, rear bumper to rear bumper. When the flag drops, they race toward each other and meet in a huge traffic accident. Drivers try to knock out all the other cars before they can knock him or her out. The spectators watching get as much of a kick out of the carnage as the drivers, picking their favorites and cheering them on.

The derby is produced by the fair and complete rules are available on the fair's website at www.bureaucountyfair.com or by calling Jason Floyd at 815-590-8873.

First place is guaranteed unless stated. All prize money is guaranteed and goes up with more paid entrants. Payouts are: Fair Class (80 or newer), $2,000 to win; Compacts, $700 to win; Wire Class with passenger, $2,000 to win; Beginner Wire Class with passenger, $700 to win, 16-18 year olds only, must have been 18 in 2014; Trucks, $700 to win (10 trucks or more). The purse will go up with more entries. Download the complete rules at the fair website.
