I agree with both posters. If it is high ground, they will generally not be grouped up, and they will bed in any cover that provides them protection from the rear and allows them a clear view out front. If there are cutovers, young aspen thickets, briar patches, blowdowns, young pines, etc. they could bed in there. Again, they are likely to be single deer or just a doe/fawn combo.
If it is low ground, they will bed in any cover where they are not laying directly in water, usually the thickest stuff they can find. Red willows are awesome, or tag alder thickets with a little grass in them. Small fingers or islands of slightly elevated ground. You can sometimes find large groups bedding together in these areas.
To me, though, it seems that big woods deer are less about a pattern and more about a home range. Within their home range, they generally go about in a fairly random pattern because they aren't disturbed all that often, so they might bed just about anywhere they find a bit of cover. If you find fresh sign, though, including beds, that is when we try to start determining ambush points along trails where we have the wind in our favor and good visibility, along with enough cover to stay hidden. If you find that stuff, then I say hunt there.
