OK - So what's the "official" rule for accompanying your son/daughter of the Class of 2013 at CBT marchback. I see where both members of the USMA Class of 1963 and USMA Alumni Parents are invited. I am a USNA alumni. Father was USMA June '43. Would they turn me down if I just showed up? I am prepared to take (and dish out) any good natured ribbing that will inevitably ensue.
