That's an awesome idea!Sounds like they need to have a "Turtle Race" where the goal is to go as slow as possible and still finish!
Last year, pack started the Lion Program, which are young kids setting up to transition to full blown Cub Scouts, Kindergartners. They participated in the Pinewood Derby, but were not apart of the actual competition and there were no winners or losers. They couldn't add weight. Was just an intro to Pinewood Derby for the next year. They all reached the finish line though.
