he may try to attend an overnight visit if his schedule allows.
My son did the overnight on an open house weekend. The rat line had broken out the weekend before. It was a good experience, but think it may have been better to see the Rat line in person to really appreciate how hard that will be. They described it but I think it is another to actually see this first hand.Highly recommend. The overnight was what removed any kind of apprehension about VMI.
