I went to the Format Festival 09 in Derby to see Mel Blas and Steve Harris who are two professional photographers based in London. They were doing a talk about a trip they took together in 2001 where they travelled from Massachussets to California photographing the locations of there favorite 70's movie sets. It was really interesting seeing there images as well as the actual map they used to plan the trip. They were really enthusiastic about the trip which came through in their talk. I did a similar trip back in 2005 when I travelled from L.A to New York so I could relate to their experience.
