I’d say you met some SE PA people, but Keara and I are bad examples. My family’s from NJ, and I lived in WV (just outside Pittsburgh) for six years, so my accent’s sort of a hodge-podge. Keara’s family from Maryland & deep WV, so she’s all over the place too. Not sure about Raemani, though.
In any case, Philly’s kind of an island, all to itself, compared to rest of the state.
