Trip to Madrid

I plan to spend a day and half doing tourists things in Madrid (such as getting insulted by locals and beaten and mugged and expoliated by taxi drivers)... So I went in the bus. Of course, since we are at a healthy 2ºC (35 F) all the bus was hermetically closed and it looked like a turkish steam bath... and I wasn't the only nerd in the bus: the guy in front of me was reading 'Feets of Clay', one of the Discworld novels by Terry Pratchett
