...about the Oyster card, I found myself pondering - who the heck came up with that name, and why? The relevant Wikipedia entry gives some info, but it still seems like a bizarre name for a travel card, and I'm not sure if the reasoning behind it stands up - although yes, I suppose "the world's your oyster" kind of makes sense (or would if national rail lines into London would allow use of the card...)

Hey ho.
