Shoulda had the Hut 100 a couple weeks ago...lol

(hi-jaking thread, but I was wondering) - Why was it that it was early September a lot (in my memory)? & was it on Friday all the time? Figured to not go against other USAC races; after DuQuoin, etc. Wonder how good attendance was for it thru-out? (Only went a couple times, and attendance was ok-ish but I figured not a big a money maker)
