Goose spends most of his time just sitting there, but every few minutes he wakes up, roars, and thrashes a bit while small clouds of water vapor roil around him.
Today, as I approached, there was a family gathered around the parapet, looking at Goose, wondering if there was anything more to him than a big green sculpture. I walked around them, leaned over the parapet, and said, "Hello, Goose." Goose roared and thrashed and steam roiled; the family jumped back and laughed; you could tell that they thought I had had something to do with it. The timing could not have been more perfect. I grinned and continued my walk.
