ATLANTA - Jimmy and Rosalynn Carter, fresh off of a trip to Nicaragua to monitor preparations for November's elections, plan to celebrate their 60th wedding anniversary Friday with a quiet day in their Georgia hometown.
In the long line of American presidents and first ladies, the Carters have the second longest marriage. George and Barbara Bush have been married for 61 years.
Jimmy Carter is 81. Rosalynn Carter is 78. They have four children and 11 grandchildren, and are expecting their first great-grandchild in September.
Friends and associates say the Carters remain as active as ever two and a half decades after leaving the White House.
"They continue to be full partners in the post-presidency to this day," said Deanna Congileo, spokeswoman for the couple. "They're continuing the work of the Carter Center, strengthening democracy, advancing human rights and ending suffering around the world."
Congileo said the Carters have no fancy plans to celebrate the anniversary - "a quiet day in Plains," she said.
The couple were returning home Thursday from Nicaragua, where they headed a delegation from the Atlanta-based Carter Center to observe preparations for the Nov. 5 presidential election.
They met with Nicaraguan President Enrique Bolanos, candidates, election officials and former President Violeta Chamorro, who served from 1990 to 1996.
The Carters grew up near each other in Plains and began dating in 1945 when Jimmy Carter was home on a break from the U.S. Naval Academy.
They were married the next year. They traveled frequently in the early years of their marriage as Carter pursued his career in the Navy, until returning to Plains in 1953.
In a recent interview with The Atlanta Journal-Constitution, the former president said the couple's relationship today is different from the early years of their marriage, when he often made decisions - including retiring from the Navy and running for state Senate - without consulting his wife.
"I was embarrassingly dominant in those days," he told the newspaper.
He called such unilateral moves "almost inconceivable" now.
