This is super nit-picky, and I'm not even sure if it's right - but the last of the graffiti-covered subway cars were pulled in May 1989 so I don't think the trains that they ride would be that covered in paint.
I'm a huge fan of the New York subway system, so I took particular interest in the Sante Fe scene.
Does anyone know where they were riding to/from? I assume Life Support was more uptown or downtown but it seemed like Roger just got up and walked over on a whim - would he have had the $1 availble to spend on the fare?
