Read a map of the area near your law school. I can't tell you how much time you can waste just trying to locate a good dentist, or figure out where the dry cleaner is. Seriously. When I cracked a tooth last semester, I spent hours trying to find a dentist who would see me on short notice.
Make a good map of where stuff is located (taking into account that there are heavy parking restrictions anywhere near many "city" law schools) and you will thank me later.
