The first Frank Lloyd Wright home is a personal residence in Blauvelt, NY ( right by Tappan Zee and Nyack). This is as far as you can get without trespassing. The second home is the famous Massaro home, also personal residence. But you need a boat or a helicopter to get to the actual house. This is LITERALLY in Lake Mahopic. 🙂
While I caretake the apartment somewhere in Midhudson, i have been taking advantage in exploring Westchester. I absolutely love strolling through Hastings on Hudson. Besides Hastings, there are also photos of Tarrytown and Elmsford.
