In the 1970s, man bought part of Washington island; now he's its only resident

Protection Island in Washington was once planned as a holiday community with 800 homes.

Marty Bluewater bought a piece of the island in the 1970s, but conservationists later fought to protect its important wildlife habitat.

In 1982, the entire 400-acre island became a National Wildlife Refuge.

Bluewater was allowed to stay and eventually became its only human resident.
