You are correct, Sir! I was a Philly guy (went to the Wharton School of Business after UM). We had tons of WaWas in Philly. I've done plenty of business in Pittsburgh but always in the suburbs (and I never drove). So, I just assumed they would have WaWas there also (obviously incorrectly). Since your post, I've done some fact checking on Wawa's site and they do not have stores in Pittsburgh (so you are correct).
However, whether it's Wawa or Sheetz (and it is Sheetz), it was less about the store and more about the "experience" of going into the store. Anyone that's been to a Wawa in downtown Philly will know what I'm talking about.
In summary, my guess is that Hykeem wouldn't enjoy the Fall or Winter in Pittsburgh at all. It is cold, grey, wet & depressing. He would probably end up really disliking the whole experience (living there for years is way different than visiting on one day). Why go through that when you can play at better football schools than lowly Pitt and have much better weather? For elite athletes, I also think it's much easier to stay in top condition & avoid injuries, if you're not freezing cold all the time and bundled in layers.
