I joined ROTC as an undergraduate when LBJ announced that there would be no further deferments for graduate students.  Planning law school, I took advantage of the law school deferment for Air Force officers.  By the time the lottery came along, I had already signed a four year active duty enlistment.

When the lottery was drawn, I received number 364.  The total immunity from the draft which that provided was of no use to me whatsoever.  It did provide a good excuse for a night of liquid entertainment with friends who had not been so "fortunate."

In a further irony, by the time I finished law school the war was over and the Air Force, awash with unnecessary officers, cut our service short.  Very short – 92 days, with many years of inactive ready reserve to fill the gap.
