Hot girls on the Alaska Hwy

I am extremely interested in a phenomena that perplexes me... REALLY hot girls can be found in some VERY small towns in a remote part of Canada. 

In both Ft Nelson (pop. 900) and Ft St John (pop. 2200), all the girls I saw were very pretty. Now, that is not all that peculiar in other places such as Boulder, CO or college towns around the world. These are NOT college towns.

I have a theory that there are a lot of bikers wearing these shirts...
