Went out for the first time this season in Colorado in an area called South Park. I have hunted the area before and know there are coyotes in the areas I am hunting because they are responding to my howl locator call. They won't come in to the howling so after a series of howls I started calling with my AP-7 throwing pup distress/rabbit distress calls at them. No success at all on 12 decent stand locations this weekend. Any suggestions? I am sure that it is my fault somehow / someway but I don't know why.
