> I've found that everywhere else, certainly in the midwest, where I live, either gets too hot in summer or too cold in winter
Much of the midwest gets both. Stifling humidity and temps often in the 90s, sometimes topping 100, for (effectively) a horrid 5- to 6-month-long summer. "Arctic blasts" in the Winter for sustained highs under 10 for days on end, lots of ice storms (and, if you do get a real, good snow, nowhere to ski anyway). 3 months total shared between Spring and Fall when the weather doesn't suck.
