Rich, I used a tactic that I read on here, to take a coyote, yesterday morning.
I went to the edge of a field, just after daylight, and challenge howled about 4 times, followed by a minute of pup whines.
He showed up in less than a minute, at 175 yards. I missed the first shot, then got him witht the second shot. A good probably-2-year old male.
I had used this tactic one other time. It worked but my rifle missed that coyote.(HAHA)
