a 4foot scrape is a small one when the rut strats to kick in. i've seen them big enough to park 2 atv's in in my area. hunt that area ,there will likely be plenty of traffic there. i'd freshen that scrape with some buck lure and kick leaves in it to see if they open it back up. you may just pi$$ off mister big and kill him.

back in early bow season i watched a 8pt make a 2ft scrape near my stand. in muzzleloader season i checked the scrape ,he had opened it up to about 5-6ft wide. later that evening i killed that buck standing in that scrape with a doe.
