Former President George H.W. Bush and his wife, Barbara, were the patriarch and matriarch of a famous political family.

The Bushes had long ties to Maine, spending summers at their seaside home in Kennebunkport where they hosted family, friends and world leaders. Inside their home, Bush kept a plaque engraved with the letters "CAVU," the acronym for perfect flying weather, "Ceiling and Visibility Unlimited."
