Are plebes allowed to leave the Yard during the Labor Day weekend break? It looks like there is a home football game that weekend as well, so I guess it is more a question about Sunday/Monday.
With it being early in the Academic Year, they probably won't have an overnight unless the team wins and the Supt grants one. They would have liberty after the game as long as they don't have duty. They would usually get Sunday liberty also with it being a 3-day weekend. Monday would usually be yard liberty for a Plebe. All of this can vary depending on leadership changes and duty schedules.
