Ruinous Ruins!

At the end of the Coastal Trail (see post below) are the remains of the Sutro Baths.
The Sutro Baths were built by one time San Francisco Mayor and rich eccentric(read:nutcase) Adolph Sutro on the very western edge of San Francisco, right by the Pacific. The baths were huge, and used seawater cycled through tunnels, channels, and pipes. They opened in the late 1890's and burned down on the 1940's. Just the foundations are left today, but it's pretty neat to explore. I would have liked to see them when they were in operation.
