I really hope this isn’t the one thing for which Canada is known.
When travelling, and the answer "Calgary" to the question "so where do you call home?" draws the fairly common blank stare, there are two things which can usually be relied upon to locate my home town on Planet Earth. My first recourse is usually "ever heard of the Calgary Stampede?" If that doesn't work, which it usually does, then the next thing to try is "remember the 1988 Winter Olympics?" Still nothing? "From Montana, drive north. It's just colder and has lower speed limits but otherwise it's more-or-less the same." Depending on how far south I am in the continental US, that's usually a good bet for finally getting the location pin to drop on the map in my travelling acquaintance's head.
I'm expecting, however, that pretty soon all that is going to change...
