Geograph - photograph every grid square

The Olympic rings commemorate the 2012 Olympic Games, when the sailing events were held at Portland. I was very lucky to get this shot with the setting sun exactly where I wanted it because not only were there several other photographers trying to get something similar, but just after I had taken it a woman came along and plonked her toddler in one of the rings, thereby disrupting the view for everyone else who had been waiting patiently to get the shot they wanted.
