<p>Lamm66 has great ideas. As someone who recently did a first visit to Pittsburgh, Falling Water was awe-inspiring but took looooootttts of time in transit. You would have to be a real building nut (like me) to find it worthwhile on a short trip. In town, we spent lots more time than we expected at the Frick museum. Art museum - good. Car museum - really fun (chat up the volunteer docents, they’re great). House tour - great. Restaurant - wonderful. Go on Sunday for brunch in October and you’ll almost want to move there. Downtown and the rivers and the incline are spectacular. Top of the incline is a wonderful spot to listen to the Steelers game feed as you watch the stadium!</p>
