The praries are cold, flat, and devoid of any cities of interest (in the sense that people visit to see the cities).

People do live in cities in alberta, but the cities are mostly car oriented. If you want to live in a walkable area you're mostly out of luck in the part of Canada between Toronto and Vancouver.

There are reasons people really enjoy being in the praries of course, but it really is a serious lifestyle choice you have to make.
