What is the smallest city in your country that everyone can still instantly recognise the name of? What is it famous for?
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.
It's a total aside, but I feel like more people should know about Shag Harbour, NS for similar reasons. That and The Shag Harbour Incident would make an excellent band name.
