I always bring my camera everywhere, and when I had a few minutes to spare before going straight home, took a peek at the highways beside the train station. Put the camera on a dangerously narrow ledge and set it to a few seconds of exposure. When I was done, a security guard blared his whistle at me to stop taking pictures. I gestured that I wasn't doing anything or setting a bomb but he was adamant.
This was the best shot I could get without Big Brother breathing heavily down the back of my neck. :)
