We all know where we can get film locally. I live in a metro area of 6 million, and I know all 3 places I can get film. However, that's a moving target as it's not the same short list it was a few years ago. When one travels, one can ask on a forum such as this: "I'm going to <blank> ..." and someone from blank can tell you where to buy film at that time.
