On my last yote hunt of this year i was using at the 45 minute mark of a set, i was doing some new coyote sounds and this big male started to do a male challenge scream at me, you could tell he was upset but he still had the presents to get downwind of the caller, i caught a glimpse of him but couldn't get a killing shot. i am sure he was the big male dog i have had off and on behind the house for a couple of years, i say by his track he may push the 55 pound mark.
