We met between platforms 13 and 14 in Waterloo Station. There was around 10 people. Someone brought a train-related tabletop game called "Ticket to Ride".
More (and better) pictures have been taken. It would be nice if the geohashers that have taken them would upload them.
NOTE: Please do not upload pictures showing my face (or please obscure the face before uploading). I'm robert, the guy in long blonde hair and in black Dream Theater tshirt or black Rush hoodie. Thanks.
