Arizona sounds tempting right now. Not a bad idea. Here it is. Arizona weather does change alot more frequent than this place that has the least amount of temperature fluctuation throughout the year. And believe it or not, it is in the GUINESS BOOK OF WORLD RECORDS. That place is the island of SAIPAN. "If you don't like the weather on SAIPAN, wait a while, then wait more, then wait more, and keep on waiting because, you are SOL and stuck with the weather all year around." Samuel Clemens little clever quote wouldn't hold water there.
Now even the island of Saipan, which is in the Guiness Book of World Records for least amount of temperature fluctuation I have seen change in weather. Especially when TYPHOON COMETH. But the high, and low don't fluctuate much from DAY to NIGHT from JAN through DEC. So..."If you don't like the weather on Saipan, take a jet north to Korea, Japan or China to see the weather change in a few minutes."
