Few oak trees may be bad for the deer, but it's good for the hunter. Try to find out which stands (or even singel trees) will be dropping acorns. The end of august is a good time, get some binos and really scan the treetops. White oak acorns are harder to see until they turn brown.

We've had "bad" acorn years when I lived in NH, yet when we shot deer, they had acorns in their rumens. So they are usually out there somewhere. If one side of a ridge has none, check the other side. Check areas of different elevation. Check trees around swamps and on knolls, etc. until you locate them. Than plan access routes for prevailing wind direction.

Early season you can catch bucks feeding acorns, especially whites as they drop earlier. Later, bucks may be skirting oak ridges or flats on ridges to scent check does that will be feeding, so look for the trails they will use, and set up downwind of those trails. You may not see the oaks, but you may see more bucks this way than if you are in the feeding areas.

Deer can't afford not to eat those acorns. By nature they are browsers, eating a variety of foods as they move. But acorns will make up the bulk of their diet when available, unless there is something more nutritious. In Indiana where I am, they feed heavily on soybeans and corn. They do get overweight, but they have low cholesterol.
