I actually didn't mind the weather in MI; it's certainly much colder in the mid-to-north parts of the state, but down around Detroit, it's actually fairly mild, and the summer is so much more pleasant than the hell of ATL summer. I think back to when I was growing up, nobody really had central air then, and my grandmother's furniture would feel *slimey* from the godawful humidity, in July/August. Really glad those days are gone; AC is really necessary in ATL! But I recall the summer that our son was born, we were still in MI, which of course doesn't have much use for central air -- but it was one of those el Nino summers, and we lived on the 2nd floor of an old farmhouse converted to a downstairs and upstairs apts -- just ungodly hot, very unusual for MI. So I bitch about the heat and humidity down here, but as long as you stay indoors, it's perfectly livable.

And it's nice that the summers run on into late September, and not even any frost until late October. By which time, we are more than ready for a break from the heat!
