I don't normally like being Mr. Grumpy old man, but it is currently 68° (20°C) and just about perfect outside, yet I hear a bunch of air conditioners running.

Consider opening yer dang windows, people!

The thing is, I know what's going on, here. Sure, some people want to keep their windows shut for allergy reasons, but it got pretty hot a few days ago so people switched their thermostats to cooling mode and simply stopped thinking about the weather.

It got to about 73° in here from insolation before I opened up windows, so some ACs would definitely be kicking on by now if people did the ol' set and forget

@TechConnectify I find it takes at least a 15 degree difference between my desired interior temperature and the temperature outside for opening a window to provide sufficient cooling. So there's lots of days where I'd be comfortable, or even a little chilly outside but would be sweating if I just opened my windows. I guess it could be possible to move enough air with lots of big fans, but it hardly seems worth it since I'll be needing to run my AC 24/7 in a week or two one way or another.
