Mmmm. Sheetz. When I'm visiting home, its pretty much guaranteed that I'm going to be stopping at Sheetz to get a sandwich at some point during my visit. As far as gas station food is concerned, this place blows Wawa out of the wawater (heh heh, couldn't help myself). Cheap and pretty fresh. The only other gas station that has better MTO's in my opinion is Get Go.
This location in particular is nice, usually really clean, and pretty prompt.
