I hadn't heard Laguna Seca mentioned until now. I doubt Miller just pulled that outta his hat.
I wonder if having just 15 races is even an option... and I wonder how much IZOD was banking on a China race as part of the 16 in the first place?
BTW... I still say to a bulldozer and jackhammer to that Mickey Mouse infield road course at IMS so it's never a temptation ever to use for Indycars... or anything else for that matter.
