Robert Bork Bleg for GMU Law Alumni

I’m doing an essay for the George Mason Journal of Law, Economics, and Politics and one of the issues I will touch on is Robert Bork’s time teaching at GMU.  First, I’m trying to establish when he taught at GMU.  I have it that his last year was 1991-92 but I’m not sure how long he was there.  Also, if anyone recalls taking any other class or other interactions with Professor Bork during that time.  I’d appreciate it if you could post in the Comments or drop me an email.  Thanks!
