Is that with all kinds of gear - or just LF stuff?
Here in NYC you regularly see folks (mainly tourists) shooting 35mm (or digi-equivalent) gear on the subway trains and stations etc.
Also, the Information booth in Grand Central Station (train terminal) is probably one of the most photographed "icons" in NYC. I figure a lot of folks must have read "A Catcher in the Rye" and are Holden Caufield (?) wannabes....
This is with all kinds of gear. If you appear to be photographing anything other than other tourists, they get in a snit.
