Man, you didn't waste any time, going into this coyote hunting head first. Can't wait to see some success pictures. All I got to say, is be ready. In other words, a coyote can show up very quickly after you start calling, so BE READY as soon as you start calling, and stay ready. They may show up at 30 seconds, but it may also take them 15 or 20 minutes to come.
Good Luck!!! Calling them in is the easy part, killing them is the hard part!!
