The Water Temple is a curious edifice built by the Works Progress Administration during the Great Depression. Its highest purpose to date, as far as we are concerned, will be the marriage of Jenn LaBrie and Zachary Shearer today, under a blazing California sun. One-hundred-twenty chairs will be set out on the tarmac by the Minnesota delegates at 2 p.m. and removed by closing at 3:30 p.m. Cooling waters flow in a pool beneath the dome, but alas, will be off-limits to would-be dippers.
