Totally off topic but is this the famous Sunil of 'covered every line
in zones 1-4' fame? I've only become a usenaut fairly recently but
courtesy of a time travelling machine called Google I've read much

those who're slightly curious as to what I mean - your past London
transport exploration exploits.
