If you haven't already, check with your school about availability to get them there. I can only speak to UGA, but they will do them once you are there for a reasonable price in the student health office and they'll even help schedule you. I also heard from some current students that if you don't have them when you get there, you might even be paid to get them for joining a study (they give you the shots, draw blood along the way to monitor immune response, you get paid). Of course, it may be different for other schools, but I'm sure most that don't require you to have completed the series by day 1 probably have something in place that might be easier than working with your local Health Department. (As an aside: I am one of the 2 rabies SMEs for my state health department, if you lived in my state I would respond! I'm actually up responding to after-hours consultations right now. We're not all bad!).
