Yesterday morning I killed this OLD dog on the first stand. Obviously a very old coyote but he came very aggressively to the call. This is on a ranch that Mike and I have called for seven years. Last week near Tilden, we called the two oldest male coyotes I have ever seen respond to a call on back to back mornings. This is on a ranch that gets a lot of calling pressure. There is no doubt that the ultrasonic frequencies have something to do with these "old timers" making a fatal mistake.
Adios,
