I am not much of a scrape hunter as I believe they are visited more during darkness making them counterproductive to sit and wait upon. I do however use the scrapes as an indicator that will lead me to a better spot in which to set up on. I will follow scrapes, rubs, trails,etc back to where the buck calls home and then set up based on his routes to and from his bedroom. Mature deer like to feel safe and when you find those areas where he feels all safe and secure you've just found yourself a spot to hang out in! My advice is to backtrack off those scrapes and lurk in the transition areas or shadows that lead to the scrapes, rubs, feeding, watering and doe activity. ANy sign is great sign, so don't stop looking and use them as ways to find a spot that will pay off vs may pay off.

Best of Luck!
