dads there worki on it together would be great.
We kind of did half and half...cutting party at one ward members house and then a drill/add weight activity at the church where the boys and dads worked together to get everyone to 5 oz a couple days before the event.
Painting and wheels were left up to the families.
Everyone ran well except for two of the most experienced families.
Unfortunately us, because I messed up and used old wheels...and the other family because the kid insisted on painting his wheels gold and the resulting friction it caused was a disastor.
