Mac,
I am sure that Hoosier will be in STL but which one I honestly don't know. We had a Hoosier dealer here in Memphis last weekend for the double school and regional. All I remember is that he is from northern Indiana. If I were you, I would email the STL region to see if they have had contact with any tire dealers. The guy that came here last weekend I didn't know was coming until he was already here. But that doesn't mean that he didn't contact anyone letting them know he was coming. In the past 3 years, our registrar usually receives an email from the tire companies if they are attending the upcoming races.
And I agree with you that it would be nice if the tire companies had regional contingency awards.

Phil
