I know what you may be thinking: I've sat over scrapes and never seen a thing. Bucks lay down all that sign at night. But this week is different. First, we're three days past the last full moon of October, a widely acknowledged catalyst for rutting behavior across much of whitetail range. Second, testosterone levels have been climbing in mature bucks for the last several weeks. Peak breeding is on the horizon and those bucks sense it; scraping and rubbing activity is as frenetic as it will be all year. Finally, late October's cooler weather will keep bucks more active during daylight hours. If there's a mature buck around, today is the first best day to get a crack at him.
