now theres a great set of rules
I gotta love the wood bugeye and the rear push bars
The boys took about six months to finish both carts. The point was to introduce them to the use of hand and power tools. They worked on everything from layout to finish. The racing was the " icing on the cake" so to speak. The boys had to work out the kinks with the steering and the brakes before we let them race.
so Bugeye ! tell us all about this extreme spot of "Bird Dog Wrangeling" as
featured in your promo photo.....Who is the world champ ?mmmmmmm! 
Not Me!!! Just to stay on topic I will say "Center of Gravity" is very important for stability.
