What on earth gave you that idea? This is summer. BCT is in full swing for the Smacks, everyone else is either helping to run that or elsewhere for another program or on leave.
It was also a week night. Unless things have loosened up a lot since my cadet days there were most likely very few cadets in Aurora that night.
Doolies should be in Jack’s Valley by now; should just be a skeleton crew, SERE students, and summer school attendees around the campus, with even fewer able to go out on a weeknight for a midnight movie.
