The former leader of the free world was caught on camera by locals traveling in a black SUV with his wife, 96, as part of the parade. They had their windows down so that onlookers could spot the pair.
"Can y’all see who is in this car? God Bless Former President Jimmy Carter and Former First Lady Carter for making the #plainspeanutfestival parade this year!!! Happy early birthday to him! #JimmyCarter99," one local shared on X, formerly known as Twitter.
"Beautiful day for President & Mrs. Carter to enjoy a ride through the Plains Peanut Festival! And just a week before he turns 99. We’re betting peanut butter ice cream is on the menu for lunch! #JimmyCarter99," the Carter Center added, reposting the video.
Jimmy was born in Plains, Georgia, and he continued to teach Sunday school classes in his hometown up until very recently. He will turn 99 on October 1, 2023; he is already the longest living president in US history.
In February the Carter Center announced in a statement that Jimmy would be moved to a hospice following "a series of short hospital stays".
"Former US President Jimmy Carter today decided to spend his remaining time at home with his family and receive hospice care instead of additional medical intervention," the statement said. "He has the full support of his family and his medical team," it continued. "The Carter family asks for privacy during this time and is grateful for the concern shown by his many admirers."
His grandson admitted earlier in August that "it's clear we're in the final chapter" of life for the former leader of the free world, with Josh Carter adding: "My grandparents have always been the entertainers. But now we're kind of the ones having to entertain. It’s different, it's just a different era."
"There's always somebody at the house," Josh told People magazine, speaking of the care the two have been given. But, as Josh puts it, "he’s still fully Jimmy Carter".
"He's just tired. I mean he's almost 99-years-old, but he fully understands [how many well wishes he's received] and has felt the love."
President Carter led the United States for four years between 1977 and 1981; he inaugurated after defeating incumbent Republican President Gerald Ford, who had stepped in for former President Richard Nixon following the Watergate scandal.
In 2002 he was awarded the Nobel Peace Prize for his work in co-founding the Carter Center which helps to conduct peace negotiations, monitor elections, and advance disease prevention and eradication across the globe.
He only sat in the White House for one term, but he became a hugely popular and lauded politician in the years after the presidency thanks to his ongoing work with humanitarian efforts through The Carter Center, and his partnerships with other sitting presidents.
In 1994, he traveled to North Korea for a peace mission on the behalf of then President Bill Clinton, and in 2007 he announced his participation in The Elders, a group of independent global leaders who work together on peace and human rights issues that included Nelson Mandela and Kofi Annan.
Jimmy and Rosalynn have three sons, Jack, James III, and Donnel, and one daughter, Amy. They are also grandparents to 12 grandchildren, and 13 great-grandchildren.
