I think that hunting scrapes can be a good idea but durring the rut i think that the best place to hunt is close to a bedding area. The dominate buck will normally cruze around the bedding area trying to keep hot does from leaving and will only leave if he has to to look for another doe. Last week i was running the camera for with my hunting patner, we got out a little before 3 and had a mature 9 come right at us before he even had his bow up in the tree. The got 25 yards and went back in the bedding area. 10 minutes later he came right back out pushing some does and my buddy shot him at 15 yards. My advice is to get as close to the bedding area as possible without spooking deer.
