Curses! As I feared, a dearth of lifeguards puts the school pool out of reach for the break. But as Chase so kindly points out, the Y only charges $5 a pop; not bad for a fill-in-the-gaps scene.
note to self: if ever I am swimming in cash, I will endow a lifeguardianship at the pool so there is 24-7-365 coverage. that pays well. :)
