I think Oklahoma (and maybe some other states) is one of the states that actually has 4 seasons. Oklahoma get's, Spring, Summer, Fall & Winter. Once you hit fall, it's all down hill meaning it's going to get cold and quick. Then you get Spring. Tornadoes. I mean I live smack dab in tornado alley then Summer hits. In the Winter, the Tulsa Zoo has "polar bear" days. Which means, if it's cold as ___ you can get in free!!!! That's insane!
