I hear all about what the tracks should do all the time. The most important part is YOU !

Take a kid racing with you. If you are taking your family or kids with you, and have an empty seat, fill it ! It's cheap entertainment , and the kid never forgets. It's easier to bring a child into the fold and start them young, then trying to get an old fart interested.

Also , don't just make it a one time thing. If your going to the track, and the kid wants to go bring'em.

Start them young, and they'll stay.
