How can I start following the racing world?

I dont know what country you live in, but in the states we have speed tv. The website is a href="http://www.speedtv.com/" rel="nofollow"http://www.speedtv.com//a they have links to almost every form of racing. Also If you are into a particular form of racing, then google it. Look into local race-tracks if you have them. There are many forms of auto racing, and true motor-heads will watch anything race. Even go-carts are entertaining. Those kids will beat and bang on each other more than NASCAR. In my opinion its easier to watch and more entertaining to "have a horse in the race" as the old timers say. Pick a driver and follow him/her.
