I will be drawing vacations for work next week. I'm looking for any insight on the dates of Sprint Week & the Smackdown. Any info much appreciated

My 2016 calendar has July 15-17 and 20-23. That would be Gas City, Kokomo, the Berg, THAT, Putnamville, Bloomington & Haubstadt unless the earth shifts on its axis. Last year, or sometime, I did an analysis of several years and gave the rules I think they follow. Right now I don't seem to be able to search for all of my own posts, but I will keep trying. A guess is that the Smackdown will be August 25-27. The big $50,000 to win wing and nonwing shows are at the Badlands Speedway the week before and I don't think they would run against that, but of course I could always be wrong. I'll try to ask around the pits in Tucson tomorrow.
UPDATE: Found it. Last year I posted that since 2007 ISW has begun the second Friday of July. However, in 2016 the second Friday is July 8, which would make ISW quite a bit earlier than usual, thus the July 15 starting date.

in 2011 the calendar fell the same and sprint week ran from the 8-16

Thanks for the due diligence Dirt & Bill. I will keep an eye on this , hoping that someone with USAC will post some hints. But I won't hold my breath on them.

Why not call USAC? 317-247-5151

You might also try to call one of the local tracks and find out when their date is. A lot of USAC people are probably out west

Indiana Sprint Week is set for July 8-16, 2016.
