Funnels,land features as others have said.circle bedding cover looking for run ways going in and coming out.Look for rubs and scrapes,rub clusters.Look for the edge of cover downwind of primary runways.Look for directional use.Are all the deer dropping down or headed toward the same area or area's.Hot food sources.
There is a lot of big woods that doesn't get used.Don't set up in area's until you have found sign that is abundant and fresh.Better to scout more than hunt until you find an area worth hunting.
Good luck!
