Ain't it a hoot!! I called my first coyote leaning over the hood of my truck, pulled off the side of the road near some old mine tailings 3 years ago and have been hooked ever since. That dog came through the tailings from about 400 yards off and the sat down about 40 yards from the truck when he couldn't find the bunny.
If you are like me you will educate quite a few before you start scoring on a reqular basis. I still get less than 1/2 that respond to the call but the % is going up. Your grandson is going to love this!
