Today's quiz :

You know that Rd. stands for road.
That Dr. stands for drive.
That St. stands for street.
That Ave. stands for avenue.

But what the foodlidoo does Tr. stand for ???
Because I'm looking for this street in Calgary, I believe, or something, can't remember, and I can't find it on the map, and it just occured to me - if we have to ask people how to get to that street when we're there next summer, if we don't know what Tr. stands for, we won't be able to name the street....
Funny, heh ?
