Spain has coolest mass gatherings.
They build human towers. They run with the bulls. They throw tomatos at each other. On Saturday, revelers packed the Pamplona town square for the launch of the “Chupinazo” rocket, a firework that kicks off the official opening of the 2013 San Fermin fiestas in Spain. The bacchanalia leads into the first of eight days of the famed running of the bulls.
