It’s one of the most famous houses in the country, and I saw it yesterday, visiting on a day befitting a home perched on top of a waterfall. It poured as we drove to the house, sprinkled while we were inside, and rained again on the way back.

Apparently, Fallingwater has also been called Leakingwater, so often does the bedrock sweat and the moisture pool. Frank Lloyd Wright, who designed Fallingwater, told its owners that drips and drops are what you get with organic architecture. “Use buckets,” he told the Kaufmann family.

I suppose when you consort with a genius, you learn to be tolerant. The Kaufmann family donated the house to a conservancy in 1963, making it possible for millions of people to experience this national treasure.

What I noticed most was the sound of the place, the peaceful patter of water slipping over stone. Or maybe it was just the rain.
