I wondered what all those black things were for. Could Park Van Ness be planning to install something on top of them? For a day or two I wondered.
Then, walking down to MetroRail on Tuesday, I saw a man working there and asked. He said that skateboarders zinging along the edge were marring the granite surface. The black plastic things were designed to deter them. And they work.
“Yankee ingenuity,” I thought, akin to spikes on window sills outside public buildings, designed to deter pigeons. “What are they called?” I asked. He told me, and pointed to a box in which they came.
