I guess I mean AFTER 1996 (the time period that I paid the most attention to the Hut 100), when the Hoosier & Hulman 100 were combined (ran in May - til 02 when the Hoosier was the only one, which was also still in May).
Here are some I can find that were not on a Sunday...I actually thought there were some Mid-week Hut 100s, and my research shows at least a couple were...again, I suppose they were looking for dates that didn't conflict...?
