Chicago attracts a lot of tourists. Most of them bring cameras. If I could give them one tip, it would go something like this: don’t stop on a busy sidewalk, bridge or walkway to take a carefully composed picture. In fact, don’t stop in walking areas at all. Turning yourself into a human roadblock is rude, inconsiderate, and just plain stupid. A lot of the people behind you will just keep walking, and I’m sure you don’t want your precious camera ending up on the sidewalk. So do everyone a favor, and move to a low-traffic area when you’re taking pictures. There are plenty of these areas all over town, but the Michigan Avenue bridge isn’t one of them — especially when it’s crammed with people due to construction on the other side.
