White lights flicker on at dusk, like moons setting on the horizon. The stench of chlorine is oddly comforting. You'll have no parking problem here, encounter few spectators, and will have to do without even the comfort of a locker room. Rinse off under the trickle of the outdoor shower instead. Once in a while, the pool will close because of rain or a team meet, but otherwise, on weeknights from 5 to 8 p.m., it's yours for the swimming. On rare days the 25-yard lanes become crowded with lean and disciplined master swimmers in their fifties. You probably won't notice them, though. This blue-green world is blessedly quiet. We swim, as we dream, alone.
