"No candy for Sandy," mocked a graffito in Delaware last year before the SuperStorm tore into the country. Elsewhere in America, zombies on surfboards tamed the angry waves. In Tokyo, activists dressed in Halloween costumes staged a march against nukes. In Germany, Halloween went commercial, while Colombia and Costa Rica threw up some of the zaniest costumes. And there were pumpkins, tons of them. And so they will be this year.
