Competitors can register now to prepare their cars for the big race.

Check-in will begin at 9 a.m. and the races will start at 10 a.m. The day’s highlights include races for Tiger, Wolf, Bear and Webelos age groups, as well as an Overall Derby and Open Class.

Entry fee is $5 and each participant will receive a patch. Those who are not involved in the Boy Scouts of America can participate as long as they have cars. Participants can register and pick up the derby rules at the Laura Fields Scout and Service Center and Scout Shop, 620 Cache Road, before the event.
