I was lucky enough to come upon a skating rink being made, the water hosed onto it making a wonderful foggy mist in the frigid air, before it froze. Luckily I put on my long underwear so I could afford to wait as a flock of pigeons wheeled around and settled in for a drink.
Total happenstance. Just happened to come by when the flooding of the rink was finished and the light happened to be sunny at that time. A coincidence, through and through.
