I agree with everyone as well.... use a tractor with a blade and move some of the downed brush and small tress so that you make trails for the deer to use. They'll find them. Once you do this, though, get out and stay out for as long as you can. So if you're wanting to set trail cams up along these new trails, do so right after you cut the trail. That way there is no pressure on the herd and they'll be that much more likely to use the new trail you made.
...and on that day when my strength is failing, the end draws near and my times has come, still my soul will sing Your praise unending, ten thousand years and then forevermore!
