Michael Tropp has met seven presidents and visited all 39 presidential gravesites. This presidential history buff just paid his respects to Jimmy Carter.

Jimmy Carter’s legacy includes working to eradicate tropical diseases in Africa, South America and Asia and to end conflicts in places like Syria, Israel and Sudan. But the late former president’s efforts also live on in the wild places of his native Georgia that he worked as governor and president to protect.

Jimmy Carter liked to eat at the Pit Stop in Thomaston, Ga. That was where the future president met a boy who would grow up to be a state trooper.
