The people that live on the road and ride freight trains, are called tramps. They try to remain unseen and are wary of anyone with a camera. With practice, I learned to approach these people and photographthem without too much trouble. Getting in this close to subjects, requires some verbal communication. In this case, I asked them where they were headed and what train they were waiting for. The man sitting on the track said, “We don’t care”. I was very impressed by that.
