The Carter home is a one-story house with 3,200 square feet of floor space on a 12-acre wooded property known as The Compound, where the Carters enjoy walking, jogging, gardening, and fishing in a pond stocked with bass, bream, and catfish; the grounds also include a flagpole given by their children and landscaping featuring plants from family and friends as well as trees and shrubs from the White House. The home was designed for expansion, originally had four bedrooms, and was renovated to include a master bedroom, a spare bedroom, an office, and a dressing room for Rosalynn, along with four bathrooms for extra guests. Its original garage was converted into an office for President Carter, and a detached two-story garage became a woodworking shop with guest quarters upstairs. The Carters receive Secret Service protection for life, twenty-four hours a day, seven days a week, and the property is secured with no admittance allowed onto the grounds, including a tall metal fence that once surrounded President Nixon's home at Key Biscayne, Florida. Children of former presidents receive protection only until age 16. The United States Secret Service, whose protective responsibilities are only half its mission, was founded in 1865 as a bureau of the Treasury Department. The Jimmy Carter Library and Museum in Atlanta present the Carters' family life from their early years through the White House and beyond, while The Carter Center is dedicated to human rights, alleviating human suffering, preventing and resolving conflicts, enhancing freedom and democracy, and improving health.
