If you’re a racing fan it doesn’t get much better than this – the Indy500. Big changes in IndyCar with Roger Penske buying the series (and IMS). We start off with Bud Denker, the President of Penske Corporation – then we’re joined by Leigh Diffey from NBC (he’s doing the play by play for Sunday’s 500). What to expect from Honda and Chevrolet – who’ll be there at the end. We talk about it all.
