It depends on what stage of post rut? If prime rut just ended I like to rattle and catch them still cruising for the odd doe. If it is well after, then I hunt trials close to bedding areas that lead to food. Food sources are always a good bet but bare in mind they have had pressure from both other bucks and hunters, so they may be moving less especially during legal times in open terrain. So if your sitting on fields and not seeing any bucks, try getting a bit further back along their transition routes.

Josh I am not much for scents however if memory serves me correct the trail end is not considered a "Estrus Urine" persay if so this shouldn't cause any alarm to passing deer.
