Needless to say - it was cold, with the ambient temperature at 2F and a strong, steady wind blowing off the landward side of the beach. When I got back to my car I dropped my keys - and was surprised to find that I could not get my fingers to bend enough to pick them up!  I did finally manage to get to car door open, though - and headed off to defrost over a cup of hot coffee with the other photographer who was shooting on the beach that morning.
