me and a friend went out yote hunting last night. we were setup 1hour before dark. we called for about 15 seconds at first then stopped for a couple of minutes then proceeded with longer calling until it reached about 45 seconds straight. we mainly used cottontail distress. we put the call down wind of us. it is a johny stewart digital caller. we stayed out until 730 then packed up and went in. any reason why we didnt see any yotes?
