As you can see from background views of the viaduct support, the three signs in these pictures are all awfully close to one another. They’re along the promenade on the north side of Mission Creek. Fifteen years ago, the major residential center on the north bank of Mission Creek was a long-term informal encampment. Now the site has a branch public library, apartments, condos, joggers, people walking small delicate dogs. The only visible evidence that this is recently contested ground is in the very many signs reproaching users of this public space to Be Good Neighbors.
