USINGEN, GERMANY - JULY 25: Llamas on a meadow of the Llamera camel and llama breeding farm, on July 25, 2013 near Usingen, Germany. Isabel Saraber, owner of the Llamera camel and llama breeding farm maintains her herd of a dozen camels and 18 llamas and offers trekking excursions in the surrounding Taunus region in central Germany. After beginning her venture with a few llamas in 1994, Isabel Saraber expanded the herd to include camels only a few years ago. Today the excursions are especially popular with corporations seeking team-building opportunities for their employees. (Photo by Hannelore Foerster/Getty Images)
