When I was in the Air Force, the dorm residents had week long shifts as cleaning and yard work crews - usually about every six months your turn would come up. And invariably the guy that was in charge of the dorm (who just supervised us, but didn't help with that kinda stuff) would tell us to mow first thing in the morning and then complain that there were clumps of wet grass everywhere. And we'd rake. And try to smooth it all out.
I guess it kept us out of trouble.
