[ChMiPr]

hey guys i'm 18 and planning on enlisting in the air force, just to get money for college if i want go, but i just don't want to waste money on studying something i'm going to change my mind on, so i'm so i can get money and hopefully get a job dealing with engineering, but anyway just wanted to know if anyone was or is in the air force, because after basic, then tech school ,i get stationed somewhere, i would love to get a 97 or 98 black 240sx, with sr20det, plus they promise you a job after you get out, don't know how good the job will be but then i can go on to college or whatever, so just wandering if any of you guys are in the air force
