I remember reading somewhere about world population and it stated that the whole world population could fit into AZ with infrastructure and all. Interesting read.
Would you kindly quit mentioning that there is space in AZ? We are quite happy with our population density. Furthermore, I would not want to be here with a bunch of folks surprised with how hot it gets in June, July, and August.
I would submit that there is plenty of wide open space in Kansas! :)
