Some recreation areas within the city, like Rock Creek Park, presently get too much use for their own good and for people's full pleasure in them because they are superior to anything else accessible to many of the city's people. This is a local manifestation of a national problem, for even sections of the great national parks, like the one at Yosemite, are presently being battered by overuse by a generation of city-dwellers anxious to come in touch with natural and basic things. In such places, people's very numbers shut them off from those basic things and coarsen the quality of their experience. The only really satisfactory answer will be to put additional, equally attractive places within reach of the same people. In Washington this means developing other pleasant areas within the city and making it easier for the city's people to get to the other parks and natural places farther out. Improvement of the river, development of extensive new parklands along the Anacostia including the Kenilworth Dump site, more neighborhood playgrounds and swimming pools, and other such action will all help to relieve the situation, which is getting much official attention and is a specific subject in the report recently published by the Potomac Planning Task Force, the group formed under auspices of the American Institute of Architects. The array of Federal, State, regional and county parks and other public areas ringing the metropolis will be more accessible as public transit improves. Another means to this end, and an especially organic and appropriate one, will be the urban stretches of the Basinwide network of hiking, bicycling, and horseback trails which will be discussed a little farther along. If, as prophets reiterate, ever-increasing percentages of the American public in the future will be living in the great cities, a great deal of nature and conservation education is going to be needed if the mass of people are not to lose all understanding of natural things and all sympathy with their working and their preservation. It cannot be entirely a classroom sort of thing, no matter how many films and preserved or caged wildlife specimens may be provided. There is need now, and there will be more need hereafter, for rich nature preserves and study centers within reach of Washington and specifically dedicated to such use.
