Sorry!

If you don't want to bring pop to the Three Rivers Festival, take advantage of places that offer cheap refills if you buy a plastic souvenir cup. Miss Piggy's Pork Shop is offering such a deal. A $4 cup (looks like it's maybe 24 ounces or so) will get you $1 refills the remainder of the festival. Their pulled pork dinner is pretty good too. For $11, it's probably one of the better, more balanced offerings at the festival. You get a pulled pork sandwich, corn on the cob, and new red potatoes slathered in butter.
