MIS, when the track is not freeze-broken, is a great track. Not a bad seat in the house, very wide.
I have seen Indy cars 4 wide in the turns, and stock cars 5 wide.
They used to have "Twin 200's", a 200 mile Indy car race, followed immediately by a 200 mile USAC stocker race. Short enough races that there was no laying back...just balls-to-the-wall for 100 laps. And most of the Indy drivers drove stockers too.
Great track, great racing.
Its a real boost for the local economy too. All 3 major series in town means big money being made. I think they should bring the Indy cars back and run them on the old road course and part of the oval.
My new neighbor asked me "what the hell is that noise" LOL. He's amazed that we can hear the cars 6 or 7 miles away.
