Just found it doing a google search.

"... 7/4 - Pennsylvania State Police removed sign along main road into gathering stating "Show Me Your Tits" after receiving citizen complaint..."
Must've thought the Gathering was taking place in New Orleans.
But this is significant:
July 28, 1997
Rainbow Family of Living LightDear Rainbow Family Participants,
We are pleased with the cleanup and rehabilitation efforts by the Rainbow Family volunteers following the 1997 Gathering on the Big Summit Ranger District. Your commitment to caring for the land was demonstrated by your thoroughness and attention to detail and the District appreciates your hard work and cooperation in meeting the resource objectives.
....
Cleanup efforts and rehabilitation were thorough and occurred mostly within two weeks following the peak of the gathering. Our post-gathering walk-though inspections showed that the cleanup volunteers were highly committed to completing the job.
Those of us on the Big Summit Ranger District appreciated your excellent cooperation on the resource issues before, during and after your gathering. Thanks again for your commitment to cleanup and restoration of Indian Prairie.
Sincerely,
SUSAN V. SKALSKI
District Ranger
Now that sounds like that Gathering was well done.
