We just found out my son got an appointment, but haven't gotten any of the official paperwork yet. I was wondering about orientation. I plan for my son to go, but should both parents go, or is it ok if just one goes? Also, what time are things over. I'd like to catch a late flight Tuesday night, but it looks like the latest leaves around 4:45. Another question I had is about getting physically prepared. He's been doing some running and weights. How much should he be doing and are there other things he should do?
