Football games in less that 100º weather?

I'm knocking the hell out of some wood right now.

Ok... not quite, I think we had one game at 99º, maybe 98º.... but this weekend they are saying we're going to be in the 80's? That's long underwear weather.

I'm surprised because I don't think any recent Sept. in year's past saw a game in the 80's. Maybe a few in the 90's.

Some year's back we had a game in Oct that was around 110º.
