This is South Wimbledon tube station. It is nearly as south as you can go on the Northern Line and the furthest south underground. It's actually in Merton but was called South Wimbledon as it had/has more social cachet. Designed by Charles Holden and opened in 1926, this is looking down the staircase between the two escalators. There for work meeting.

Oh I so wish I had taken this - what an accomplished image! I adore the mettallic finish and the symmetry - who says compacts are not serious cameras? Fav? You betcha!
