Snapple Cap # 156

I just drank a Snapple Mango Madness and my "Real Fact" cap trivia said that the swimming pools in the U.S. contain enough water to cover San Francisco.

What the hell does that mean?

Do they mean that if San Francisco was flat there would be enough water from all the pools to wet the entire surface. If so, at what depth?

Or do they mean that if we built a wall around the city of San Francisco and dumped all the swimming pools in there it would be enough water to cover all the hills and buildings?

Are we counting only personal home swimming pools? Do Olympic size pools at gyms and schools count? How about water parks?

It all sounds homophobic to me. Why San Francisco? Why chlorinated water? Is it some kind of subliminal message that we need to baptize all the gay people?

Snapple cap facts are so annoying.
