There's an interesting migratory phenomenon in the engineering buildings noticed, I'm sure, by staff and faculty at about 20 to 30 minutes past the hour. It's rather amusing to notice from the inside, when it's not frustrating. Here I went to the bother of learning where to go, and it does me no good at all. The only way to get to class is to follow the herd - unless you know the shortcuts through the buildings that other people don't. And since "short"cuts rarely are... just go with the flow. Or be the person who's 30 seconds ahead of everyone else, and fight your way against the crowd on your way back from the drop box.
Either way - that's engineering.
