A colleague of mine is visiting from Bulgaria. He brought me, as a gift, a picture book entitled "25 Beautiful Places in Bulgaria".
He arrived on Sunday, and has already had a little time to explore the area. What had been most amazing, he said, was the smell. "Nobody told me about the smell."
The smell? I wondered if maybe he'd wandered a bit too close to some of the salt evaporation ponds near the Dumbarton bridge or something.
No, no. He meant the beautiful smell of flowers and grass. When you live here, he asked, do you just get used to it?
"I think we must," I said, sniffing the air.
I think this is an underexploited tourism promotion angle: "Come to the San Francisco Bay Area. We smell nice."
