I’ve attended a number of Indycar races @ Ky.
It’s bloody hot on a sunny day even if the air temp is 80.
The stands are built into a south facing hillside covered with concrete that acts like a heat sink.
Today in Indy (not too far away) is hot, humid, unstable air so we may see big thunderstorms this afternoon.
A fortune could be made selling cans of beer for $5.00 apiece along the route..
A “tweet” says that the #3 car in the Nationwide race failed the post-race inspection - to low in the rear - and to expect a penalty next week.
