If he is frequenting the area there is no need for active scrape lure unless you really want to. The does in the area will do that naturally for you. I've muddled around a little bit in scrapes before (that I wasn't going to hunt) and the bucks quit using them. Any scent you leave around can only hurt. Not worth the risk if you feel confident he's happy in this environment. Definately hunt it though. Place your stand a good shooting distance away from one of the scrapes so if he comes in, he'll stop and present a good shot.
