Gone to Pittsburgh – what should I see?

I won’t be blogging for a week or so. I’m away for a stretch, including a family vacation to Pittsburgh.
I’ve been there covering campaigns, but never really spent time in the city. So I’ll finally get to PNC Park, Fallingwater, and, I hope, the Johnstown flood museum on the way.
You got other ideas? Feel free to leave some suggestions for museums, recreation, and dining.
And tell me the truth: Do I really want a Primanti Brothers sandwich?
I’ll back with you after Labor Day.
Enjoy the end of summer.
