I am new to this forum and computers for that matter. It is interesting reading the wide variety of theories and ideas here.I am no expert, biologist or any such thing but I have been hunting for 33 years in basicly the same area and was lucky enough to have a grandfather that was a cattle breeder/farmer/hunter, we would go out and watch deer for hours on end. He would collect dirt from scrapes before rut started and store it until mid summer then start making moc scrapes in late summer, when a deer starts using them it becomes a central marking area for the local deer, does will also urinate on these scrapes during summer the more the better. then right before the rut bucks start making there own scrapes to single each other out and then when they have established there presence they start searching each other out and fight for dominance, If there is more than 1 mature buck using the same scrapes and they will also keep checking them for signs of estrus thats why the more does that visit the scrapes the better and by introducing scent from other scrapes into one you can force that buck into daylight searches for the mystery bucks and if all works right you will be waiting for him. I have used the hawgs scents for starting the process then transfer dirt from other areas in oct, it saves alot of money and you get the same effect.This is the results of the scrape setup I use, this is the 4th trophy I have taken with this method. with a little scouting in late spring for these big bucks comfort zones and setting up close to that area you can take these big boys with confidance.
