Lovely postcard, look at those cars!
The Canadian band, The Guess Who, have a fairly famous song recalling their memory of Saskatoon called appropriately enough, "Runnin' Back to Saskatoon." The live version (recorded in Seattle) has the singer giving the intro saying there really isn't much happening there.
I knew you'd know Saskatoon! I haven't heard the song, I'll see if it's on youtube :)
