Ah, Rich - I haven't heard the term "bubbler" in years. I moved to Racine, Wisconsin, from Detroit in fifth grade, and got in trouble with the nuns the first week of school for drinking from the forbidden bubbler. I think it must have been the Bubbler of the Knowledge of Good and Evil - but I didn't know what the heck a bubbler was. That's one word that hasn't spread very far - I'd say it's used in just a few counties of southeastern Wisconsin.
