The Bethesda Terrace, located in Central Park near the east 60's and 70's, was a popular spot on Sunday February 8th. Saturday it had been warm, in the 50's, and on Sunday it was warm up until the afternoon when it became cold and windy again. People were out jogging in shorts and shirts though. It was freakish.
So the Bethesda angel is part of the Bethesda Fountain that blesses the Bethesda Pool (in The Gospel of John). Her wings are pointy and pierce the sky.
