Got Scouts?

Any of you have cub scouts? I do and it was recently Pinewood Derby time. I would love to have a fun shirt to wear for it, but there aren't very many out there. So while I was at the last Pinewood Derby, I saw a car (or 2 or 3) using coins for weight. **Lightbulb** I got an idea for a t-shirt. I want to make one for next year that has a picture of a car loaded with coins and the caption "Pinewood Derby...Where the money is!"
Let me know what you think or give me another idea if you have one. Maybe I'll make 2 and send you one ;)
