Best Themed Car

We will be having a best themed car contest, judged with a decibel meter measuring the enthusiasm of the crowd. This contest is exactly as it sounds. Dress your car with as much “flare” as you possibly can. You can even dress up to add to the glam. For example; in past years we have had the Peace mobile with a hippy driver, the pink Cadillac with Elvis driving, Ghostbusters car with the Ghostbusters driving. There aren’t really any rules, simply dress up, show up and enter. This is a family event so please keep your theme appropriate. You and your car will be displayed in front of the grandstands for judging and you will have to walk across the arena to a 30 second clip of your theme song while being introduced by the announcer. This takes place at 7:00 to kick off the Derby. It only takes about 15 minutes. You will need to pick a theme song for your car. This is a fun way to get the crowd to pick favorites in the classes and gets them more into to the actual derby. It is fun and a great way to pick up some extra cash! All props used for the contest must be quickly removed before entering the arena for your class. You must be a contestant in the Demolition Derby to enter the Theme Car Contest.
