If you're going to San Francisco this weekend, there's something new at the Racer X booth that you don't want to miss. Free Racer X supercross trading cards!

This year we decided to pay tribute to our past 250 supercross champions. The trading cards have been designed by our good friend Marc Estabrooks and you can't buy them anywhere, but we'll give you one free if you stop by the Racer X booth.

The cards will be available at every round of the 2006 AMA Amp'd Mobile SX series, with a different rider featured each week.This week's feature rider is Jeff Ward. There are a total of 15 different cards.

Want all 15 SX trading cards? You can go to each round of the SX series or you can just renew or sign up for a new Racer X subscription at the RX booth. Also when you sign up you will get a Chad Reed cover poster, limited edition Team USA calendar and the newest copy of Racer X Illustrated. So look for Fubar in the San Francisco pits and get yourself a limited edition Jeff Ward trading card.
