Jeanne and Bob Donald lived in Valdez, Alaska, in 1989 and dealt with the fallout of the Exxon Valdez oil spill. Now they own a cheesecake shop in Gulf Shores, Ala., a town hit by the BP oil spill. Bob, who was a mental health professional in Alaska, tells NPR he's considering doing it again because he expects to see the same psycho-social problems as he did in Valdez.
