I think it was SAMUEL CLEMENS that wrote that saying. "If you don't like the weather in NEW ENGLAND, just wait a while. It'll change". I see this saying has come to signify most of these United States. Clemens lived in Connecticut a good part of his life where he wrote most of his famous quotes. New England signifies the good old American PURITAN work ethic and "Do it yourself" life style and strong beliefs in religion. This was America's cradle. Where it all began. So the weather saying for the most part is significant of the whole United States. I think a local twist here and there adds to its charm. Like "If you don't like the weather in Texas, wait until you come out of the frying pan by October or November and then you won't be so friggin miserable."
