I wont go any where near his roost anymore unless i want to scare him away from hens he might be with. I instead set up where i know he wants to go and wait there; field, strut zone, food sorse whatever. as for the ATV noise unless your hunting a farm where they are used to hearing them, plan on parking a good distance away. they might be love sick but they arent stupid. there are aftermarket mufflers that you can add on for extra stealth.
