You'll find me inbetween the stalls of my good mate Paul, with his excellent 'PublicGriefJunkie' emporium, and Anthony of 'Meaningless Slogan' fame.

You'll only need to get to the canal bridge on Camden High Street itself, then walk up the ramp into the East Yard of Camden Lock, towards the Market Bar/Lock 17. Look to your right as you go, and all is easy as you like, just as you see in my little diagram.
See you there.
