The staff of Racer X Online will be on hand at the Phoenix supercross all day today, tweeting updates and reporting here on our website. If you're on Twitter, be sure to follow us @racerxonline. If you're not, you can read all of our Twitter updates at www.twitter.com/racerxonline, or in the Twitter box on the bottom of our home page. We'll be using the #sx hashtag on our tweets and encourage you to do so as well.

If you'll be at the race, watch our tweets for you chance to win a very cool prize. More details on that later.
