PRI's The World: 12/18/2015

Marco Werman has one more day on assignment in Kenya, and today he meets some of the very few women who serve as safari tour guides in Kenya. We also hear from one of the country's few female stand-up comedians, and we say goodbye with a Swahili version of Adele's hit "Hello." Meanwhile, in Germany, The World's Matthew Bell looks at whether or not police there are prepared for a Paris-style attack. Plus we'll have the story of a couple celebrating their 50th wedding anniversary. It stretches across continents — courtesy of a scrap of paper that nearly ended up in the trash.
