Spotted...

The mile munching monster that is Vesalius riding past Whitechapel tube on his George Longstaff as I waited for a friend at 6.30. Was going to shout DAS then realised it has gears and by the time I'd decided what to shout he'd zoomed off.

I thought that was you! I looked straight at you and for some reason I decided it was just an imposter :p
