Underground Urban Fox
This cheeky chap was snapped at around midnight on 5th December 2009 at Walthamstow Central tube station in London. As I got of my train I'd seen him dashing down the escalator, and when the workmen shoo-ed him back up again he sat near the top for the moment - enabling me to grab these two pics.
I added this one, taken on my iPhone, to Twitter today at around 2pm - 7 hours later and it's received over 13,000 hits. Incredible. Now that's the power of the interweb. :)
UPDATE: By the hometime from work the next day it had got 35,000 hits and appeared both on Metro and the Daily Mail online and was featured on BBC London News. By Tuesday it was printed in Metro, Daily Mirror, Sun, Daily Star and the Daily Mail and was on Telegraph online. By Thursday it was on the BBC's One Show. Incredible!
