Pretty much the best thing about our trip to London for the boys was for some reason the number of escalators they got to go on. Unfortunately I'd left my 14mm back at our relatives house and it would have been better for this. It's Just such a lump to carry around when you are not sure what you'll be photographing.
We were so busy visiting everyone that I barely took any shots while there and most of the ones I did take were on escalators. I'll have to go down for a few days on a dedicated photo trip in a couple of months.
