YOU MIGHT say the trouble started at the Ivy, which is a moving picture house in Cave Junction built like a big quonset. It's the only show in these parts, and most of us old-timers up here in the timber country of southwest Oregon have got into the habit of going to see a picture on Saturday nights before we head for a tavern. But I don't think old Doc Yoris, who was there with Lew and Rusty and me, had been to more than two or three shows in his life. Doc is kind of sensitive about his appearance.
