Howling at the moon
When we were living in Washington, we raised chickens for eggs. Since we were pretty far out in the woods, there were plenty of predators, so we were careful to keep the chickens locked up at night in the chicken house. Many evenings we had an outdoor fire going in the fire pit, and it was wonderful to sit outside, warm from the fire, and enjoying the spectacular star show. One evening, as we were relaxing by the fire, we heard coyotes starting to howl and yip off in the distance. Gradually they got closer, until they sounded like they were quite close to our chicken house. Ken decided rather than shooting at the noise, he would try to drive them off using animal psychology. So, he gradually started yipping like the coyotes, repeatedly working himself up to a full fledged howling crescendo. It worked like a charm, we heard no further noise from the coyotes, and the chickens remained safe in their house. Jim and Jonathon were very impressed with this display (as was I!), and from then on worked on perfecting their own howling at the moon.
