Tourists on a whale-watching boat look as a guide sights a whale off the coast of northern Dominican Republic, in this photo taken March 15, 2000. Every winter, thousands of humpback whales swim thousands of miles to reach the warm, shallow waters off the Dominican Republic. The whales come from as far away as Greenland to mate and have babies, starting to gather in December. Tourists start coming in January and last year some 32,000 came for the spectacle.(AP Photo/John Riley)
