Experiment Update 2

I spent today running round town, pulling letters out of my bag at random. Because it was indecisively raining, I had to abandon the 'in sight of a postbox' plan, so I put them in indoor or fairly sheltered places:

tokyo_mb: Your letter was left on a wall on Chrisp Street in East London.
clarisinda: On a chair in Chrisp Street Idea Store.
mouse262: In an East End pub called The Widow's Son.
cartographer: On a glass table in the lobby of 1 Canada Square (the tall, pointy Canary Wharf building).
casca_2u: On a Northern Line train at Highgate, heading north.
randalf, smorgasbord, boingley, sparktastic: all left in and around the British Museum by my esteemed research assistant elethe.
primavera: given to my new research assistant hoshuteki to be left somewhere in Brixton.
thessalian, I tried to leave yours on the tube at St John's Wood, but the whole bloody carriageful of people chased after me going 'you forgot your letter, you forgot your letter', and I had to look grateful at them. :) So points for social responsibility go to them, and I'll find somewhere else to leave yours!

Experiment update 3

Some more distributed tonight on the way to, at and on the way back from a rather fun Nano-warmup-meet:

neil_scott: on the Piccadilly line at Bounds Green. I thought someone had picked it up almost right away, but they just put it in the windowsill.
dakeyras, kesstrel, mooism, davefish: given to another wonderful research assistant arachne to be distributed in Shepherd's Bush.
the_maenad: on the tube back home, left at Holloway Road. I'm getting better at this 'looking like I've dropped it accidentally' schtick.

Lots more to go!
