Boomer Sooner! It doesn't break the bank to live in Oklahoma - quite the opposite. As with most agricultural states, housing is cheap, and food is right on your doorstep, so it costs less. Add this to the list of places you can acquire housing and eating for around $15,000. Ask someone from outside of the US what they know this state best for, and they'll probably tell you it's the musical of the same name. The state presumably agrees - they took their official state song from it.
Whereas there are plenty of places you'll find natural lakes in the USA, all the ones you'll find in Oklahoma are human-made, which is quite a staggering achievement. You won't find a state that takes college football more seriously, and nor will you find one that's quite so frequently visited by tornadoes. There's no 'average' weather in Oklahoma; you're either baking in the dust, or you're in the middle of a storm.
