Agreed. I can't imagine what that would be like. Wake up one morning, and find out that you don't owe Uncle Sam those four years after all.
ROTC folks, take a long hard look at your options. It is kinda rough in the private sector right now, but damn if this isn't a great opportunity to walk away with a free education.
Hell, if you want to walk, but still want to keep one foot in the military game, go talk to your local ANG or AF reserve unit and see what they have to offer.
