I was in London again on 22nd - 25th January and on Saturday 23rd we headed into town and took a walk through St James's Park, in the neighbourhood of Buckingham Palace. There are lots of geese and ducks on the lake and plenty of squirrels that will take any food you care to give them.
From St James's Park we headed over to Trafalgar Square. This meant navigating the traffic. Fortunately there are plenty of pedestrian crossings.
