Film Odditites: Yaddo

When a writer writes..how much of what surrounds them effects the final product? I believe it informs the process somehow. Next time I watch Synecdoche NY I will keep Yaddo in mind. Yaddo is an old estate in upstate NY that is for serious writers to work on their craft. For two weeks Charlie Kaufman worked on Synecdoche NY there...when I went to Google Earth I noticed that Yaddo is in Saratoga, NY..about 300 yards away is the race track..the famous Saratoga Race Track. I wonder if any of this somehow finds its way into the Escher-like experience of this great film?
