This map was inspired not only by the movie, but I had stumbled on information that Susan's house was not a fictional place, but a real house here on Long Island. My husband and I took a ride and there it was, the only difference was there was an addition upstairs. I didn't put the addition in my sketch. I actually forgot it because it is in the middle of the roof, so my drawing of the house is mix of 1946 and 2017. It was awesome, all of those years seeing that scene in the movie and when we drove down the street, it was like going back in time. I couldn't nail down the Walkers apartment nor the Brooks Retirement home, so those are guesses on the map based on location information gleaned from watching the movie several times. Those are the two locations marked as "fictional."
Season's Greetings and Happy New Year!
