Trikes will require more space at both ends of your commute. They will go slower for a given effort than a 2-wheeler. The are harder to lock securely, since the frame is typically a simple crucifix. Car traffic seems to intimidate trike riders more than bike riders. At least the Minneapolis area has quite a few trails.
I would not bicycle (or tricycle) commute unless I could park inside, preferably in my office. And of course it will attract people. It will attract conversation if it's in your work area, and people will want to sit in it.
