You are right about hunters being lazy. Most people won't venture more than about 1/4 mile from vehicle access.
One place to start is the US Geological Survey topograhical maps. They are very helpful. They show conturols, forests, open areas, trails, roads etc. They are kind of out of date. They don't show all the logging roads in the forest where I hunt, but they do give a good indication of where the areas that don't have roads. Below is the link to their website. they have a list on the sight of where you can get them in each state, or I think you can order them directly from USGS.

Also, get some arial photos, those help when combined with the topo maps. I don't know where you are from, but lots of counties in WI have done arial photo flyovers in the last few years.
The thing to do is scoutthese areas out before the season, so you can find areas that are both remote and good deer habitat.Generally, as you go deeper in, you will find fewer other hunters, but be assured, you aren't the first person who has thought of this. As I scouted areas this fall, I waspretty deep in and I came across the best ground blind someone had made. It looked like alog cabin with walls, a bench seat log roof withpine branches and everything.
Once you plan to venture in so deep in the woods, a GPS would be handy to help you get your way back to the truck. I want to get one of those for next season.
The thing about getting so deep in the woods, is that its a long way to drag a deer.
