yes, i think Carter did try to do quite a bit for breaking our oil dependence, promoting cycling and general physical fitness... my memory's flaky here, but weren't many long-distance trails like the Pacifc Coast bikeway created from federal funds in the late 70s? and i also vaugely remember the "President's phsyical fitness" test or something in school...
ok, i searched and it was started in '53 by Eisenhower, but Carter did contribute: "President Carter speaks at 1st National Conference on Physical Fitness. In 1979, physical fitness and exercise become one of 15 priority areas in a national health promotion/disease prevention initiative" (
