I visited in September. Basically you go in the morning and a few officers give you a presentation (recent grads for me, there were three 2nd Lts). Then they take you to hand off to a cadet. HNeedle so graciously escorted me. You attend classes w/ them, and basically shadow their day. You eat at Mitch's as well. HNeedle took me to English and Calc XII or something, lol. Had free time to walk around and look at the athletic complex, chapel, etc.
If you can get out there, I would suggest doing it, especially if you can't make it to Orientation.
P.S. Does anyone know if we get more info on Orientation? We really haven't gotten much on it.
