Underground underground

Following on from our maps of the world's subways, Meg Pickard has blogged on the calculus of finding the best spot on a London Underground train. She claims that you may not know you're doing it, but if you're an experienced Tube traveller you're actually playing a sophisticated game of three-dimensional strategy. I'm sure you could adapt her principles to your own local system, if you have one. In some ways, this also echoes some of the issues raised in this morning's pissing game.
