It's Pinewood Derby season again and I kinda enjoy making derby cars. This year, my youngest son and I made an awesome car for his bear den division. It came out great and I'll do a blog post on that one as soon as I get some good pictures.
We also have an 'open' class where the rules are a little more relaxed. Last year's car was fast and I actually won but not because I was the fastest. I was really impressed by a c02 powered car that another dad had made. He had trouble keeping it on the track, but it was REALLY fast.
