Chat with St. Petersburg GP winner

The IndyCar Series leaves ovals for the first time in its 10-year history, hitting the streets Sunday at St. Petersburg, Fla.

The 1.8-mile, temporary street course figures to challenge the fitness of a field of drivers who -- for the most part -- haven't raced the bumpy streets in years.

Bryan Herta, a road racing veteran from his old Champ Car days, won the pole in St. Pete, edging Helio Castroneves.

But defending IndyCar Series champion Tony Kanaan lurks just behind, making Sunday's race wide open.

So watch the action today at 3:30 p.m. ET on ESPN, then log onto ESPN.com and chat with the winner right here afterward.

You can send questions now and we'll have them waiting for the winner.
