Oh its nothing secret, lots of people do it, its just something i e never tried before. Using coyote vocals only. Ive had a couple nice open reed howlers sitting around for a couple years (the one i used is in the pic next to the dogs face) but ive never actually used them. I guess i just didnt feel confident that i could make the right noise, or even use an open reed call well at all. But i decided i needed to try it out, so the night before i went out i practiced with the howler in my house, then practiced some more in my truck on the way up there.
I got there and sat in my truck waiting maybe 45 minutes for enough daylight to walk without tripping, and when i got out of my truck to put on my coat and load my rifle i heard sond howling a little ways off on the other side of a creek. So i snuck across the creek and found a perfect spot to set up. i made 1 howl then just set the call down and waited. Id say it was only a max of 3 minutes (i forgot to look at my watch to time it) but probably less when the yote popped up over a little terrain feature about 80 yards away, trotting in looking for me. First time ive ever tried to call one in that way, and i nailed it. Got skunked the rest of the day though.
