Time not given. A 13-year-old boy working at a kennel in Williston, Florida heard a humming noise, and noticed that the dogs were attempting to hide in their pens and whining. As he went out to investigate the area turned red with illumination, and a bright red disc-shaped object hovered only 20 feet over his head. He felt heat coming from the object. When he returned to the dog pens, the dogs barked at him and would not let him inside. (Sources: Robert Gribble, International UFO Reporter, May 1984, p. 16; MUFON UFO Journal, May 1984, p. 11).

Camped near a ridge the witness had been seeing red, blue and green object go over the ridge many time late at night. This night he camped on top of the ridge directly northeast of his home. He took his binoculars and saw an oval disk shaped object with blinking lights and making a low pitched humming sound. It was over the ridge in a small clearing. He did not see it until its lights came on. It hovered there for a while, he looked through the binoculars and saw what appeared to be a porthole or small window, and he could also see a humanoid shaped head wearing some sort of helmet. This frightened the witness who decided to climb down the ridge and go home.
