This cold morning at the Presidio, elegant terns wheel over the lagoon at the edge of the San Francisco Bay, screeching like a fleet of squeaky bicycles. In the distance, fog blots out the top of the Golden Gate Bridge. On the strip of beach closest to the water, dogs chase tennis balls into the surf. And in restored sand dunes, volunteers yank non-native plants and pile them in trash bags. Around them, buckwheat blooms, its round purple globes adding color to the gray day.
