Hunt the does. Scrapes are not so reliable due to the fact that most (not all) scrape activity occurs at night.

I agree with USAF hunter, but will add:

If you have scouted and determined doe bedding or feeding areas, I would hunt them. Another good area to hunt would be well-used travel corridors between the two. You may get the opportunity on a buck that has intercepted the doesscent trail and come by you. From experience, the best time to hunt the travel routes would be early morning (get there before dawn) and late evening (couple of hours before end of legal shooting light).
