I'm pretty sure I-96's show will be on the 3/8ths. It's not exactly the most spectator "intense" track since the grandstands & flagstand are about 30 feet from the actual racing surface. (Youtube I96 Speedway and you'll see what I'm talking about.)

Hartford will be a great show. Track is the same size as Terre Haute, only a LOT more banking and wider surface.

I'm concerned the Michigan people don't have any idea what USAC is all about. I went to a Silver Crown show up at Berlin (Grand Rapids, MI) in 2010 and there were about 400 people in the stands.. if that. Anytime you ask someone what they want to see in Michigan all they ever want are A) Late Models or B) SOD Winged 360's. I don't think I've ever talked to anyone who has said they wanted to see a USAC show. Both 96 & Hartford going to need a strong Indiana following for USAC to be profitable... or it will be the last time USAC is ever seen in the Great Lakes State.
