Flashback: 1969 Draft Lottery

I've been reading David Leavitt's most recent novel, The Body of Jonas Boyd. One character's 1969 military draft lottery number is four, and he decides to escape to Canada. This got me wondering: what would my lottery number have been, and would it have been low enough to mean I would have been sent to 'Nam? Turns out my birthdate was #27 in the 1969 lottery; my husband's was #30. Had we been born 15 years earlier, does this mean we might have met somewhere in the Mekong Delta instead of in New Haven?
