September 1, 1939: "Ranger Perrin (Penticton) cannot use a radio in his office owing to strong local interference. He has a lookout, Campbell Mountain, which is radio-equipped and also has a phone on the local circuit. By the simple expedient of placing the phone receiver close to the speaker of the radio on the lookout and holding the phone transmitter close to the radio microphone, Ranger Perrin can be put through direct to any of his radio-equipped lookouts, and carry on a conversation direct from his office via phone and radio." (Forest Branch News Letter)
November 1949: "This spring, an open air drive-in theater was constructed at Penticton and the screen faces directly towards Campbell Mountain Lookout. During the idle evening hours, the Lookoutman is able to see the movie. Of course, he must use binoculars and the set-up lacks sound." (Forest Service Newsletter)
