Basically just repeating everything kmonte has said, but figured an extra perspective would help to back it up. 🙂 I've actually spent the last three years (off and on) in Oklahoma, and will be moving there for a full-time job in two weeks! I'd say the weather is pretty similar to OK, but I'm just south of Norman/OU and don't know any of the other areas' weather. FL doesn't get as hot, as in very rarely over 100, but the humidity is KILLER. I'd take a 115 day in OK over a 95 day in Florida any time, and I work outside with little shade. It rains wayyyy more in Florida. Pretty much every single day in the summer, but like kmonte said it never lasts. I've literally had it be downpouring with black skies out the front window of my house, and totally dry with blue skies and sunshine out the back window - not even an exaggeration, it's actually really cool to see. Winters are fantastic because they don't really exist. They're exactly as kmonte described.
Cheathac, rent is what I consider reasonable. Easily pay 500 or less per person if you live with roommates. 1 bd apartments usually go for 600-1000, which is a huge range but depends on how nice.
Ilikecake, I have very little equine as well, for the same reason. But I'm hoping they won't mind as long as we're strong candidates in other areas.
Glad to see so many natives and OOS-ers! Best of luck to everyone!
