But I'm thinking of including on one of my upcomming trips to get to Falling Water. Is the only way to get there by rental car? I don't usually rent a car since I stay and work downtown and have been able to get around easily by foot, cab or hotel shuttle. Is there any public transportation or tour group that will get me to Falling Water? If rental car is only option, is it an easy drive? I'm from Houston so I'm used to traffic but don't particularly enjoy driving in cities I'm not familar with if I can help it.
