When you are hiking far the north up the coast -- say, Mt. Wittenberg -- you can just barely make out the city to the south ... it's so tiny ... and you can distinctly see "the big bug." Or, from Mt. Diablo, or from Russian Ridge down on the peninsula. This is in addition to being visible from practically everywhere within the city itself.
It's an amazing landmark and, I've come to be quite fond of it.
