I graduated from college in May 1969 on a 2-S deferment. I was almost simultaneously reclassified 1-A and took (and passed) my physical at the Chicago induction center in June or July 1969. I also got married that summer and was accepted into grad school at the University of Wisconsin. Despite my local draft board’s prediction that I would be drafted  by September, I registered for school in Madison anyway.
In December 1969, they held the first lottery. I seem to recall that it was a tense and yet, almost a "what will be will be " attitude among grad students. I was very lucky and ended up with No. 352.

When I got to Madison I supported the war. By the time I left in 1971 I opposed it. I still think about the guys who went to Viet Nam while I did not.
