It was decided to devote a day to collecting stations. From this decision several conflicting plans emerged; to leave things to chance and draw stations names from a bag, to chose a section of the line and hit it station by station to grab as many places as possible in the shortest time, to travel out to the furthest reaches of the District Line and explore a little of Epping Forest.

Plan B wins, after considerable debate. Hammersmith and City Line gets the guerilla treatment as I want to get my nails done at Shepherd's Bush anyway...
