I have several friends who joined the Armed Forces right out of High School because they "could find anything better to do." Some of the skinniest, weakest guys I know joined the Marines because of Recruiters! I think a Recruiter for your local EMS in high School do some good. They can come and talk to classes, site at a table all set up for him during the lunches, things like that, just like the Military does. I'm sure you'd get plenty of students who are looking at the Military, but don't want to leave home, or looking for a job to get them through college that doesn't involve Iraq, or who are really unsure what they want to do yeah, and sign up out of interest.
Yeah, Rid, if your EMS can offer to pay for the training and such, I'm sure you would have plenty of kids join up right out of high School!
