In the United States, I’d probably name Oregon City, the famous end of the Oregon Trail and the first city founded west of the Rocky Mountains during the pioneer era. Its population is only 37,000.
Edit: I got it - my bet is Charlottetown, PEI, because those Anne of Green Gables books were wildly popular on the international market, and I imagine fans tried to find Avonlea on a map and learned that Charlottetown exists.
I’m probably still wrong, this is actually kind of a tough question.
Edit 2: Nah I change my mind, maybe Gimli, MB because the Gimli Glider incident did garner quite a bit of attention.
