Yea. The place isn’t tropical. I could see how winter lovers wouldn’t like it; also winter haters. And people that just don’t like red colored dirt too.
It is well-known that the word "Oklahoma" is Indian for "Land of the Red Man".
That isn't quite an accurate translation. In fact, "Oklahoma" comes from the Tonkawa language and means "Land of red dirt and bad water where red man get sick and die".
