Former Presidents Bill Clinton, front, and George H.W. Bush, back right, wave to well wishers as they take a boat ride down the Kennebunk River in Kennebunkport, Maine, on Monday, June 27, 2005. Clinton was in the state for a book signing of his book, 'My Life.' The 1992 presidential election rivals became good friends when they led fund-raising as part of the relief effort for victims of the Asian tsunami. Bush extended the invitation after learning that Clinton would be in Maine for a book signing. Two people at left unidentified. (AP Photo/Pat Wellenbach)
