Green Bay is a modest industrial town best known as the fabled 'frozen tundra' where the Green Bay Packers win Super Bowls. The franchise is unique as the only community-owned nonprofit team in the NFL; perhaps pride in ownership is what makes the fans so die-hard (and also makes them wear foam-rubber cheese wedges on their heads).
While tickets are nearly impossible to obtain, you can always get into the spirit by joining a pregame tailgate party. The generous flow of alcohol has led to Green Bay's reputation as a 'drinking town with a football problem.'
Otherwise the town is pretty quiet. It has a couple of intriguing museums and a well-known brewery by the stadium, plus a nice patch of cafes on its riverfront.
