Humidity and heat are a problem for some folks. I thrive in it and hate anyplace cold. I was born and raised in Indiana and I was miserable 8 months out of the year. If it's below 60 I'm freezing. I won't go north in the winter and I have lots of friends up there who won't come south in the summer. Hey, it'd be awfully crowded if we all wanted to live in the same place.
