My whole family of 6 will be there! Just getting notice my wife will have off of work so I will be signing up. After the event, then we will continue the vacation for the kids... maybe the Lakes boating or something.
I hear July 2nd at Indy the F-1 race will be there.
Oh, and FWIW, my first impression of this year's event (occurred at the Pocono event) was we would be racing at THE INDY track but it is probably my ignorance they don't have a road course incorporated like Pocono does. Mostly nostalgia sake but I like racing on any road course.
BIG QUESTION: Will there be babysitting services during the road course and autocross events? I think that would be nice for those spouses that really want to watch - maybe a couple teenagers can get together to pick up some cash. Just a thought...
