We have around 12 different awards that go out to specific types of cars (Most Patriotic, Best of Show, Best Engineered, Best Car That's Not a Car, Best Paint Job, Smoothest Paint, etc.). The cars get judged by a few parents after the check-in deadline but before the races start. At some point during the races they hand out these awards and call each scout up to accept the award. The MC will ask the scout about their car. It's very cool.
I have suggested that when these awards get handed out that we show the car on the big screen so everyone can see it but I guess it takes too much time to get that arranged on the computer.
We also run an Outlaw class when all the regular heats are finished. These run while the times are getting calculated and sorted out. Anything goes except combustible gases. We pull the timer off the track for this series to keep it from getting damaged. Anyone can race Outlaw so the sisters can get involved here.
We have concessions with a local pizza shop selling us solo pizzas very cheap. Chips, pop, popcorn machine, candy. Sam's Club has been very good to us with donations. Just ask them over a month in advance because they go through their donation request forms once a month around here.
We have our Scout Master MC the event and he is very good. He had already looked over all of the cars prior to racing starting so when the cars would get staged he would point out interesting things about the cars at the gate. This helped kids with slower cars to get recognized too during the racing and made each heat interesting for those not racing that round.
We get 2 practice runs prior to final check-in. One person stages all cars the entire day.
We also have DJ playing music.
