So my current photography topic is 'trains'. This topic is supposed to net me 12 finished prints and 720 negatives by the time the class is through. Today I thought i'd shoot my local train station, as I get on and off of there every day. Within minutes I was approached by 3 Port Authority Police who inform me that it is not legal to shoot mass transit locations without permission. I explained who I was, gave them my student ID and drivers license, explained my project, and since I only got 3 shitty test shots, even offered to erase the pics. (I see the one cop 2-3 times a week, so i'm sure he'll recognize me from here out...) They were very nice and polite and all that, and let me know that the rules are the same for all stations in and around the Philadelphia... I'm a little pissed, and a little demoralized. Besides the obvious frustration from having been confronted by law enforcement, I'm now not sure what to do about my photo project... Anyone have any ideas on what you could shoot for 9 straight weeks?
