Just north of Market Street, there's a traffic island in the midst of the intersection where Hayes and Larkin and Market meet in a typically confusing San Francisco way.

In the middle of the traffic island, there's a lamp post.

Around the base of the post, someone skilled of hand and observant of plants has drawn in chalk long flower petals that look a little windblown, so the lamp post seems to be the large, looming center of a flower in a windy field.

There is a more direct, islandless way to cross that intersection, but I used and paused on the island because of the remains of a sprain. I took the slow boat, and someone left me a flower.
