When it is 91° outside at 10:20pm, it is beyond July Indiana weather. As others have said, many are going to show up and drink alcohol (which causes more thirst) and not drink enough water. They will possibly get heat stroke. Then you got drivers who can't wear shorts and a t shirt.....understandably, you will get some fans who are not happy, but even though I could afford a trip to LPS this week, it is not happening for me for a few reasons, main one being the heat (other being I got to work on my moms van).
