Well I really don't know where to start, but I'll try. I hunt D7 but the eastern edge. With the season in late September, the deer are still pretty much high (where it's cool & there are fewer insects to deal with). You need to get into the mountains as far as the roads will take you. Get away from NF camps and basically civilization! Do a bunch of scouting this summer. Get some good maps and hike the trails that go east and up higher. Do some backpacking and fishing in the backcountry this summe, always looking for deer...sign too (tracks & poop). Remember the deer are active mostly at night, early morning and late evening. They will mostly bed down during the heat of the day.
Hope this helps some. Good deer hunters work hard at learning their craft, deer habits and finding good place that produce animals. When you put everything together, you will do well...just keep at it.
