I was one of them there "college punks" who got drafted in '67. They must have been scraping the bottom of the barrel if they thought we'd make good soldiers.
Then after I took their tests, they kinda scrtched their collective head and said, "Which school do you want to go to?"
I had to sign up for another year, but the school was almost a year long. Essentially, they were paying me to go to school.
... and learn about computers and rockets.
Talked to the Air Force, they kept pushing games and theory, but said if I had my heart set on mechanic they could fit me in. Either "tomorrow", or "one year from tomorrow". Neither was what I was looking for.
Talked to the Marines... "Boot's a b*tch. Training is hard. No guarantee's. But we can get you there in about six months... sign here..."
The rest is rather pathetic history... ;-)
Good thing too or we'd be traveling to Mars in hot air balloons.
