Which is the only town to end with a exclamation mark?

I know that Westward Ho! in Devon, England has an exclamation point in its name (what a worthless bit of knowledge) but when I looked in Wikipedia for how the town got its name, there is also mention of a town in Canada, Saint-Louis-du-Ha! Ha!, which has two exclamation points in its name. More to the point, both town names end in an exclamation point. Better change the question.
