My son is in Cub Scouts this year and we had to build a Pinewood Derby Racer for this years derby. We came up with a Semi-trailer racer design. He took a Design award at the Pack Derby in January and was invited to complete in the divisional competition which was today. I am proud to say he received a trophy for 2nd place in the divisional competition. A long time judge at the competition said it was one of the best designs he has seen in years. Way to go little buddy!
