Because of other hunters and the amount of area the coyote utilize, I assume coyote have had encounters with hunters. I do pay attention to where I see others park,walk into. If I can avoid duplicating what other hunters have tried/done, I feel it gives me an advantage. Usually this means a different wind direction or calling near a different travel path the coyote use.
If during the day, coyote immediately start running if I even start slowing down the truck. I do more scouting to find the best way to drive in/park. I seldom park in the open, even at night. No loud exhaust, door slamming. Walk as quietly as possible.
