I've Got a Double Topper?

Helen's message says, she said some lovely things about us. She also has an unsolved mystery you may be able to shed some light on. So listeners, helen sets us the challenge to find a group of people between mid teens and mid thirties who were camping in old fashioned canvas bell tents. And though helen was suspicious that they were occult because they wore unusual costumes. They all dressed in the same shade of brown. The women wore ankle dresses with long sleeves. The men only wore loin cloths, brown, bulky loin clothS Sounds very, very errotic, indeed.
