I looked everywhere for a higher resolution version of this infographic, but this was the best I could do.  The accompanying article in PhillyMag talks about how Wawa has gone from a gas station/convenience store to having a near-cult following in the small area it inhabits.  I still remember the first time I saw the Wawa on 38th and Spruce before even coming to Penn and wondering what a Wawa could possibly be - now I can't even imagine not having one!
