If there is anything good about a Tube strike, then it's the fact that it forces you to travel by bus. And to go by routes and see things that otherwise you wouldn't. But it take's twice as long as usual to get home
The windows are grimy and covered with algae, but I have to admire the graffiti artist, not for the style, but for the fact that they managed to get up there. Because nobody is ever going to clean it off.
