Every year, Medellin puts on a display of lights in the lead up to Christmas. This year, the theme was flora and fauna, for which Colombia is famous. It is number one or two in the world in terms of diversity for amphibians, birds, butterflies and orchids and represents more than 10% of all species on Earth. Sandra and I spent one of my last nights in the country wandering through Parque Norte enjoying the various displays. Some are 3D; some are 2D moving pictures; some transport you underwater, but all are spectacular.
