Just finished binge watching this show ... I wont embarrass myself by telling you how long it took me, suffice it to say, I had some time on my hands due to unforeseen circumstances and I took advantage of it.
I lived in Pittsburgh from 79-84, got married in Bethel Park (yeah, I concur, it's the 'whitest place on earth') in 81 at 18 years of age. Was there for the Superbowl of 80 in which Pgh won ... incidentally, right after the Pirates won the World Series in 79, it was a huge deal for PGH, the city went nuts, no wonder triplets were conceived then, ha!
One scene in particular had me congratulating the writers ... it was when Jack went up against his Dad about his Mom, and his Dad said "two of yous deserve one another" ... yous is very popular in PGH ... that told me the writers had a handle on life in PGH.
The bar scene, the roads, the homes, yeah, they all had a definite PGH feel, they pretty much captured it. Bravo show.
