I would like to visit Wright's Fallingwater which the web says is three hours from PIT, however it doesn't say in which direction. So, what's the nearest reaonable airport? Or might I want to come by Amtrak from somewhere? I'm not fond of driving. It looks like the tours are early morning. Where would I sleep that is convenient?

I am in WAS a few times a year, could add on to those trips, and will be in NYC next August.
