I can tell you I really really wish I had tried to get something together for the years it was at Indy, Union Grove, Byron, Cordova, basically making a circle around Chicago. I didn't, now my dad, who would have been trunk monkey had passed and boohoo. Make it happen for yourself if you can.
I sat out on the street for two years watching it pass close to my house, only got to do a few days of spectating...
The funny thing about science is that if you change one miniscule parameter you change the entire outcome to the way you want it.
