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!

@TechConnectify Pittsburgh has some of the worst air quality in the country, and after participating in a study looking at how outdoor air quality affects indoor air even with the windows shut in the middle of winter, I have become a “closed windows forever” person I’m afraid.
