Then they grow up. My 14 year old and I go out every Tues. night from 4-10 (we leave at about 7 when it gets crowded) and run our Karts at the local Karting road course.
Here are some pics of him shaking down his new Formula World Kart at Moroso Florida.
You guys are about 4 years from this. I have a 4 y/o that will be out there next year.
