I haven't read all the responses, so I apologize if this is repetitive.
We live in Putnam Valley, a very small town in Putnam County. Very woodsy, some farms, etc. But we're within ten minutes of the Taconic Parkway and Peekskill train station (Hudson line). There is a Montessori school that is 15 minutes away, and the Garden Road School, which is an excellent Waldorf-type environment, that is less than 10 minutes away.
I love where I live. Miles and miles of hiking trails and lakes... we keep chickens in our backyard... people are kind and most know each other around here.
Good luck on your search.
