I really don' t worry about cover scent a whole lot, I try to get down wind of where I think they may come out. Yotes usually come in w/in the first minute or last sequence. The ones that come in quick usually aren' t too worried about their surroundings, it' s the ones that take their time that you have to watch out for, they will nail you if you make one wrong move. I usually move about 300 to 400 yards away if I try to call on the same piece of land. Watch all around at all times, those dang things will sneak up on you before you know it from the opposite diection you think they will come from. It is always good to have a buddy so you have two pair of eyes looking in different directions. It is also funner to share a hunting experience with a buddy. Good luck!
