Bucks start scraping in earnest a week or two before the first does come into season. This is the best time to hunt over a scrape line or a primary scrape. A scrape line is just that; a line of scrapes showing the buck’s travel route. You can find a flurry of scrapes where the buck’s trail intersects the does trail.
While I like to set up as close as possible to a scraped line, I prefer my set to be 75 to 200 yards downwind of a primary scrape. A big buck will more commonly travel downwind of a primary scrape and merely scent check it.
