Spa is by far the track I'd most like to visit (and drive). Budapest is a great city but the Hungaroring is kind of a boring track imho. Monaco has the history, Monza doesn't do much for me as I prefer a more technical layout. Suzuka is a neat track with the Spoon and 130R and Istanbul Park is another one I'd like to see/drive.
Grosjean is out for Monza and I suspect that there will be further fallout. If he'd taken out a back marker it would have been no big deal. But taking out Alonso and Hamilton is a bit more high profile. Then again, knocking out Alonso was perfect for tightening the driver's championship so maybe Bernie will give Roman a bonus
