Agri-Service Demolition Derby

**Demo and Power Wheel entries start Saturday, July 6th.  You can go to the rodeo office (green gate), or register online starting at 10:00 am, July 16th.

The office will be open for ticket purchases starting July 6th, Thursdays, Fridays and Saturdays, from 10:00 am until 6:00 pm.  During rodeo/demo week (August 15th – August 19th), tickets are available at the office from 10:00 am – event close, as well as the “BLUE” gate from 9:00 am – event close.

We are having two nights again so we’re not so cramped and don’t run so late on a work night!  The Demo Derby is a Moses Lake phenomenon-the cars are sliding, spinning, rolling, and of course CRASHING!  This event is guaranteed to provide hours of entertainment for all ages.
