Planning to visit London? At the link are some extremely useful maps for visitors to our fair city. The length of time it takes to walk between stations for one; and the stations between which it is quicker to walk than to travel between by Tube, for another.
The Going Underground blog (link above) has a rather spooky regular Friday feature: strange garb worn by Tube travellers, taken surreptitiously by "Annie Mole" and her fellow Tube spy bloggers — with associated Flikr area. Take my advice, don’t wear Ugg boots or anything metallic if you visit London and plan to use the Tube. You have been warned.
