Maybe you might go out to the races just to see how things are. With this in mind, I offer a few tips for spectating. If there is a national in your area, go to it. It might surprise you who ends up enjoying it. You'll also help promote the sport you love and possibly earn some extra respect.

Remember back to when you first watched a race, particularly a novice class, and thought how slow they were.
