Pittsburgh ??
But I'm a bit *biased* - only lived there some 20+ years!
South Hills = Mt. Lebanon

I remember...

Riding the Duqusne Incline...



And the "Trolley" over the Smithfield Street Bridge,
then thru the Mt. Washington Trolley TUNNEL...



Here's "My 42/38 Trolley" in Downtown - THE Place to Shop -
before they built the suburban Malls...
