Your much better off to find a trail of them, a scraping run. One scrap that is not acompanied by a major trail or sign is just a place where a buck had a fancy to make a scrape. May never come back to it again. A scrape run is where the guy frequents, but most likely at night. Hunt this area during and just before the chase phase of the rut (first week or so in Nov. around here). He will be coming more by more often to see if any does are hitting them. And of course, look for the big scrapes, big tracks. Often times there are multiple bucks using the same line. I have pics from my trail camera where 9 different buck hit the same scrape.
