As an aside, I'm in the current postcard exchange and I received one yesterday with some interesting information on the back.
It was a picture taken at a professional American Football (NFL) game.
The author went on:- "that the NFL Films shoots 16mm film at every game. They shoot about 23 miles of film every week during the football season. They are the largest purchasers of Kodak film in the world".
That's 37 kilometres of film every week, which is a fair bit.
Any comments on that information?
