          Dear Griggs: 
 
               Your letter regarding the influence of the 
 
          airplane on wilderness areas is well timed. Your 
 
          premises are certainly sound. As to your recommen- 
 
          dations, I agree with number two completely. Re- 
 
          commendation number one seems to offer difficulties. 
 
          If I arrived at the border of a wilderness area 
 
          under the regulation you suggest only to find that 
 
          the person before me was the last who could be ad- 
 
          mitted that day or that week I would feel very much 
 
          upset and I think justifiably. Making reservations 
 
          in advance would seem to be the only way out and 
 
          that would involve very complicated procedures. 
 
          I realize the necessity of the protection you are 
 
          seeking but this particular method does not seem to 
 
          me to be workable. 
 
                                   Sincerely yours, 
 
 
 
                                   William S. Cooper
