Although you are missing Friday it's Saturday that really stands out in my opinion besides race-day. The Firestone Fast 6 and knock-out qualifying rounds provide some great action. I'm not sure whether Star Mazda is all that great. It doesn't have a TV presence at all or at least not in Canada.
In fact, if you don't follow it in written reports on indycar.com you don't notice it but Indy Lights has a strong presence. As long as I see Ferrari at least once this week and preferably a race I'll be happy. I know I shouldn't but I never really pace myself over the weekend wanting to see all. As long as I have tons of water handy I make it through alright. I'm glad they went 90% open-wheel and 10% Ferrari though for support races. Still I think the word NASCAR even it was the regional Canadian series would sell more tickets. I wonder what the real story with them and Canadian Touring Car not being back is. I guess not enough butts in seats but dunno.
