Two-time Indianapolis 500 winner Helio Castroneves in Turn # 6. Castroneves captured the pole at the Detroit Belle Isle Grand Prix, but crashed during the race. Both of Grand Prix promoter Roger Penske's cars are having tough seasons. I think it's safe to say that both Castroneves and Hornish are having disappointing seasons. (I fully expect Hornish to make the NASCAR jump in 2008. Who that leaves to drive Penske's #6 Indy Car becomes the question.)
An aside, I wish there was some seating along the back stretch. One of the appeals of Indy Car racing is the speed these cars can obtain. When I went to Michigan International Speedway a couple of years ago, the average speed was over 200 mph. While the road course does bring the speeds down, I'd still love to be able to watch the straight away portion.
