Minnesota's 4th largest city (the Mall of America is 3rd) is a hell of a lot more good lookin' than it sounds. It's a mini San Francisco built onto the hillside overlooking the largest lake in the world, Lake Superior. Famous for both its international harbor and unique aerial lift bridge, Duluth and its outskirts have been the background for Disney's IRON WILL and, farther up the scenic lakeshore, for 20th Century Fox's THE GOOD SON. And they know how to make a good hot dish up there, too.
