If any racetrack deserves two races during Sprintweek, it's Kokomo. The racing is the best in the state, Haubstadt included. Unless you like slide jobs and crossovers, one after another, for 30 laps straight.
I agree with the people who've posted something about trying to keep the dates in some sort of geographical order. I even think you could get half of the tracks on their normal nights, like this:

Wed: Lawrenceburg
Thurs: N. Vernon
Fri: Bloomington
Sat: Haubstadt
Sun (Day show): Terre Haute
Mon: Off
Tues: Off
Wed: Paragon/Putnamville
Thurs: Liberty
Fri: Gas City
Sat: Kamp
Sun: Kokomo
