That is a great scanner, but for listening to the teams at the track, i like this one better:

As a footnote, the one I have now is just like Joe's, with a 1000 channel capacity (way too many). My first scanner was a sport cat, and it was better for racing because it gives you 20 Priority Channels, which cut's time searching when you have so many teams to listen to.
