I have figured out the definitive difference between Baltimore and Northampton, which comes in the form of two opposing bagel prosciutto sandwiches. Northampton's bagel prosciutto sandwich comes with sliced green apples and sharp cheddar and dijon mustard and is on a wheat bagel. Baltimore's comes with cream cheese and tomatoes and is on a seasame bagel that somehow tastes like an onion bagel. Also the two visions of prosciutto are a little different: Northampton's is very thin and lean, while Baltimore's is thick and marbled. I don't even need to tell you about where to eat these bagels, the crowd in these eating places, or the streets outside, because simply telling you about these bagels tells you all that other stuff. These differences represent themselves without value judgments.
