Hey, that's great! You're going to love being around that spectacle. Disco is bringing a strong team! Contador, Leipheimer, Hincapie and Popovych. It's going to be hard for the other teams to compete for the overall, but the sprints will be pretty interesting. With no real climbing to speak of, the race is going to be about winning the time trial and containing the dangerous breakaways. Look for Slipstream to give Disco a run for their money. Danny Pate and Tim Duggan were 2nd and 3rd in the US TT Championships last weekend. HealthNet and Toyota should get some stage wins with their sprinters.

Try to make it to one of the stage starts if you want to really get up close to all the teams and racers as they get prepared for the day's race.
Have fun. And take lots of pictures!
