Mid America has a number of classes including an open scout, open Kids, and open Adult class for people who want to race no matter where they are in the country. You fill out the entry form, there is a cost tied to sending the cars to them for racing, and they race the cars on race day and you can see how your cars do against all other people sending in from all over....the open scout one even breaks it into dens (tigers vs wolves vs bears etc)
We send in by Proxy....pack the cars in car carrier boxes and ship them USPS over to the race (include return shipping label and they will ship them back to you without a problem and include any prizes or trophies you win!).
The best place for information is on the forums under Local Racing Events. Xanthrum (Greg) is the one person responsible for posting much of the information and responding to any questions you have, and is the coordinator for this event.
If your interested definitely give that forum post a read thru and even check out the Mid America Pinewood derby website for information, rules, updates, pics from last year etc....
Its a pretty fun event too if your able to get out there, lots of door prizes and trophies for the racers in a various classes....There was also a "pro" class race out at the same time there on a separate track for those builders that have been building and league racing.
Similar to the league racing, the race is also webcasted so people who could not attend but mailed cars in can watch the races live from their home computer.
Its just another chance to be able to run that PWD car you spent so much time and effort to build with your son one more chance to compete before mothballing it for the rest of its existence....that is unless you also send it to NPWDRL league races which I also recommend!!!
