When I manage to get up early to shoot photos around the water, I notice that's when Pelicans are out and about. They seem to be flying somewhere just after dawn, as though in a morning commute. However when I took this it was just after dawn and extremely foggy. My guess is the pelicans were fogged in, in the same way aircraft get fogged in and the airport closes. They just seemed to be sitting here waiting for the heavy blanket to lift so they could be on their way. At least someone was smart and decided to sleep in.
