DIY Pinewood Derby Track

I demonstrate an easy to build pinewood derby track that features mechanisms to release the cars and to designate the winning car. I only purchased a 1/4 inch sheet of plywood and used scrap wood for the rest. I looked and couldn't find anything similar so a am sharing my original design with the Boy Scout community. I had 3 boys in Boy Scouts so I built many cars over the years, but this is only my second track. Much more interesting than building cars:)
