Although Rightmyer imposed certain rules from the very first Roundup, the rules developed as the number of attendees grew. Eventually, he included the rules on fliers mailed in advance to invitees and posted them by the registration area at the campground. [/ Copies of several of these fliers appear in the appendix to this report, Section C, at 27 et seq. ] One of the first rules prohibited fighting. Other rules banned fireworks, political activity, persons under eighteen years of age, and use of video cameras. Still other rules stressed that people were responsible for their guests and that people should not talk to outsiders about what occurred at the Roundup.
