For today's Geo Quiz we wanted to know how many miles it is from Guantanamo to Havana, Cuba. The answer is 500 miles. American Richard Fleming knows that personally. He walked from one end of Cuba to the other and chronicled the experience in his new book, "Walking to Guantánamo." Anchor Katy Clark speaks with him. And for our Global Hit we feature the music of the late Cuban musician Polo Montañez.
