Drive 3 to 6 hrs south (depending where you are, maximum assuming you live in P-town) to a decent state and ask for a Taylor Ham, Egg and Cheese with saltpepperketchup (that's one word) in most any small bagel shop.
I first heard about pork roll at a Trenton Thunder game where it's a big deal. I ended up trying a pork roll sandwich and enjoyed it. It's one of those things I wouldn't eat all the time but I still get the sandwich every time I'm at a Thunder game (which is usually once a year).
