You may have come across an old station building on the south end of Half Moon Bay (on the way to the beach), preserved as a small   home.

This was the Ocean Shore Ry's Arleta Station, somewhat fancy by OSRy standards. It was planned as the center of a real estate development, but Arleta never took off.

The official Half Moon Bay station was closer to town and fairly humble. It still exists, but has been moved. It's current location turns out to be close to a school where Nate has been playing basketball on Saturdays, so today we took a look.

The big white building in the background is the Johnson House, and is 160 years old.

Across the road is a nice farmhouse with barn, etc, still a working farm. Interesting subjects in their own right.
