Oh yes, join the USAF. I did when I was 17. But in hindsight, I wish I were still in making decent money. At my current age (40) I would have retired already & have a retirement check every month. But I tell ya, the best fun was with my friends there. I went to Japan, Australia, & Philippines. It was good to see the world. Even if you only do 4 yrs, go ahead & get the experience in computers or avionics. Then hopefully when you get out, you can land that decent job besides tending bar. I mean it really, go for it.
