Lyon reappears for one last block between the Palace of Fine Arts and Marina Boulevard. (It sort of continues on the other side of Marina, but is called Lundeen, of all things)
I didn't take this photo on the same day as the others. I missed this last sign, and wasn't really sure where Lyon turned into Lundeen. And I wrote up a description saying it was just as hard to find the end of Lyon as the beginning. But that was wrong. It's just that the sign is kind of buried in that tree, and if you look at it from the wrong angle, you can miss it.
