Ive seen scrapes start to show up the last couple of weeks around field edges. I dont beleive these are what you would call (pre-rut) scrapes. To my knowledge deer will have a "community" scrape(s) that are used all year long. but to answer your question the ones you will find that are being made and freshened now through november, those are the ones that you want to set up on, in hopes of whacking a trophy! hope this helps
