I was in a college town when the lottery was held. I saw the numbers listed on an Associated Press teletype that had been set up in a downtown storefront. Fortunately, the store was next to a college bar which soon had an overflowing crowd.
I kept my deferment until 1972 when I enlisted having used up my college deferment. After 4 years I returned to college and got my Masters on the GI Bill which paid the full freight.
