Eisenhower retired to the place where he and Mamie had spent much of their post-war time, a working farm adjacent to the battlefield at Gettysburg, Pennsylvania, only 70 miles from his ancestral home in Elizabethville, Dauphin County, Pennsylvania. In 1967 the Eisenhowers donated the farm to the <answer>National Park Service</answer>. In retirement, the former president did not completely retreat from political life; he spoke at the 1964 Republican National Convention and appeared with Barry Goldwater in a Republican campaign commercial from Gettysburg. However, his endorsement came somewhat reluctantly because Goldwater had attacked the former president as "a dime-store New Dealer".
Who did Eisenhower donate his farm to in 1967?
