really?

I know Philly is enormously bigger than Pitts in population; but I was thinking more along the lines of economy and impact in the state of Penn. Clearly, Philly and Pitts are the major players, which Harrisburg pulling and controling some of the strings.

I think it fits OKC-Tulsa in a way, because you combine Philly and Harrisburg (getting OKC) and Tulsa would be analogous to Pitts (economic power with some great positives Philly doesnt have).

Oklahoma is unique in that it has two very prominent cities (statewide) and for many years OKC didn't really step up and be the big city. that has changed, and I think the Philly Pitts analogy fits beautifully. Pitts (Tulsa) is no slouch, great city and would otherwise be tops, but Philly (OKC) is clearly the big city in the state.
