I chose VMI because I liked the atmosphere. It's not in a large party town, so I don't have that distraction. I'm locked down much like a prison, so I'm forced to study, not go out drinking and partying every night like I would have at a normal college. I also wanted and needed the discipline. I am not the same person I was when I Matriculated on 19 August 2006. That six months of the Ratline was tough. Mentally, physically, spiritually. No if, ands, or buts. No matter where you go, it will be the same way.
Also, there is something to be said about the type of person it takes to get up at the crack of dawn to go and stand in the freezing cold, and then march down to chow, only to face a full day of classes and other duties. In my first four months at the Mother I, I did more than any of my friends from high school did in their entire freshman year.
That being said, no matter where you go you'll only get out of the experience what you put in. If you go, go full tilt and put out 100%, no less. Best of luck, and I hope to see you straining in the Fall.
