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.
Pueblo, CO from tv commercials or maybe Walla Walla, WA from Bugs Bunny.
Walla Walla, it was also a lyric in an Offspring song.
Also in this song
Witch Doctor - Ooh Eeh Ooh Ah Aah Ting Tang Walla Walla Bing Bang
Pueblo, CO
Mostly because it is (or was) a publication distribution hub.
Virtually no one outside of the US will have heard of it, though.
I haven’t seen a TV ad in years; who’s out there talking about Pueblo?
Walla Walla Washington! It was one of ten airports (not sure exact number, but few!) in the first release of MS Flight Simulator. Also Yakima.
