This is the underground, the little blue sign says keep to the right. This is because people who live and work in London run every where. It's quite strange to be going down, or up an escalator, to have people running past you, and I'm not talking fast walking here, I'm talking running. And another thing, this picture doesn't do it justice, but these escalators are frighteningly steep. Having said all that the underground is brilliant, getting from a to b couldn't be easier, and it's cheap too.
