Thanks to many of you for the recent feedback. But I cannot even debate with people claiming to be South Jersey if you don't know about:
1) The Mummers
2) The Curse of Billy Penn (A friend had to tell me about this - this must be my North Jersey side)
3) The name of the state's official fruit . . . notably South Jersey residents score much better on naming the fruit than North Jersey residents, undoubtedly because it is predominantly grown in the south.
Not to try and follow a tacky internet quiz, but if you knew all three, you are from South Jersey.
