I use drippers, they draw bucks in between 10am in the morning and noon. The drippers also really turn on doe's to mock scrapes. Once that happens you can see bucks anytime during the day if you rattle. If the buck thinks doe's are in the area , he will be in for a daylight spot n sniff if he can't locate the doe's at night. Once the buck makes a competeing scrape you have to hunt on it until he checks it again. I recommend cutting a real scrapes communal branch and wireing it over your mock as well. I have heard of digging the dirt in a scrape and placing it in a bag to spread on your mock scrape, but haven't tried it yet. I have seen many bucks check my mock scrapes near a doe bedding area. WLRC will send you a book on making and hunting mock scrapes for free if you ask them.
