Captain David Clemens, 64, who has been on the waters for 40 years, said: "We have more resident whales in Prince William Sound than I've ever seen in my life. Whatever they're feeding on must be healthy enough." Colleen Stephens, 37, who runs boat tours in the Sound, said: "The first couple of years we had to convince people not everything was covered in oil and the places we go are beautiful. People would ask us to go and see where the tanker was." Her father Stan Stephens, 76, was one of the first to respond to the Exxon Valdez disaster and is now chair of the Alaska Travel Industry Association.
