Though technically speaking my first picture is in SW17!
But I did set out from my door and that is squarely in SW19.
SW17 - rooting Tooting Broadway
SW19 - Tooting Bec
SW12 - Balham
SW12 - Clapham Sth
SW4 - Clapham Common
Frist sight of central London - Canary Wharf
SW9 - Clapham North
SW9 - Stockwell
SE11 - Oval
Helicopters - 4 Gazelle's whirring in the sky above me on the bridge. Tops!
