When and where did Hillary tape her "I'm in" video?

Mark Finkelstein posted a fascinating observation of Hillary's "I'm In" video which was released today. Go to NewsBusters to see the video and pay special attention to the view outside the window. Curiously, all the plants and trees are lush with green leaves and there are even yellow flowers in bloom...in January? In Georgetown? In Chappaqua?

Surely there's a reasonable explanation. Maybe it's just that pesky global warming.
