I was always against war growing up, yet after a conversation with someone from the neighborhood who joined and it staightened him up good - as by his own account he was headed to a life of nothing but trouble (him and his 2 brothers were not to be messed with) - I saw its appeal. I wasn't a head cruncher like them, but saw it would have a positive effect and we should all enlist for a cpl of yrs at least.
I regret not having done so, but did consider joining the ROTC to go to a certain school, as my folks wouldn't allow me to study what I wanted and I couldn't afford school and being on my own.
