I was passing by when I noticed two swans in the pond. I was going to keep driving but then thought, 'let's see what pictures I can get'. By the time I was ready to snap some photos the swans had decided to get on the ice. Actually a better scene. But you can't ask them to 'look this way', or, 'move a little to the left'. So, you wait for the best picture you can get, and, then take lots of them.
They did cooperate, to a degree, and there will be more opportunities.
