Bogotá's mayor has suspended bullfighting in Bogotá's Santamaria Plaza. But the fiesta brava continues in other Colombian cities and towns...

If you've passed the intersection of Carrera Septima and Jimenez Ave., you probably noticed the crowd of men standing on the sidewalk bunched into little groups.

They've been called ghosts, memorials to the dead, even visiting extraterrestrials. They are the green men (and a few women) standing on rooftops and balconies in La Candelaria. They include a model, a shoeshiner, an acrobat, a musician (without his guitar) and others of unclear profession.

The drizzle envelops us in Bogota all too reminiscent of a dull October morning in London. As the grey clouds obscure the ridges of the Cerros Orientales, the telltale pines and eucalyptus vanish, and you could be almost anywhere but for the thin oxygen, the red transmilenio buses and towering billboards of Aguila girls.
