Tower Bridge from a Thames river bus - 26 5 2015

The River Buses are not designed for sight-seeing. Most of the accommodation is inside the cabin, with only a small area at the stern that is open. That area can get crowded at times when the weather is good and this snap was taken while I turned around on the bench seat at the back. This is why the picture was taken at an angle. I could have cropped it down to make a neat horizontal view, but some interesting bits would have been lost!
