Have half a day in Madrid - where to?
I was there last May and Puerta del Sol was mobbed with protesters; it's probably even worse this year. It was hard even to get to the Plaza Mayor without taking a detour -- the streets were filled with people and police.
Be advised. Maybe you;'d like to photograph the protesters?
Here are my pictures of Granada, Seville, and Cordoba from that trip. I didn't include any pictures from Madrid...
