I planned to stay longer in Madrid, however after my brother returned to London I caught wind that it was the Día de Cataluña the following morning and so I wrapped up this stop to catch another night bus heading for Barcelona.  I misread my bus ticket and ended up at the southern bus station, soon realising that I needed to be 6km north at Intercambiador de Avenida de América.  After the feeling of urgency kicked in and hastily traversing the city, I made it in time. As I stepped off the bus the next morning could hear the beginnings of the celebration coming for the Arc de Triomf. I couldn't wait to finally see a Castell, a human tower!
