"MISSION 66 is a forward-looking program for the National Park System
intended to so develop and staff these priceless possessions of the American
people as to permit their wisest possible use; maximum enjoyment for those who
use them; and maximum protection of the scenic, scientific, wilderness, and
historic resources that give them distinction.
Construction is an important element of the program. Modern roads, well
planned trails, utilities, camp and picnic grounds, and many kinds of structures
needed for public use or administration, to meet the requirements of an expected
80 million visitors in 1966, are necessary; but they are simply one means by
which "enjoyment-without-impairment" is to be provided.
Under this program, outmoded and inadequate facilities will be replaced with
physical improvements adequate for expected demands but so designed and located
as to reduce the impact of public use on valuable and destructible features. It
will provide both facilities and personnel for visitor services of the quality
and quantity that the public is entitled to expect in its National Park System.
It is intended to assure the fullest possible degree of protection, both to
visitors and resources."
