If you guys are serious about this hunt I'd highly recommend either 1. An early season hunt (second or third weekend of September) and look for oaks on ridges. Look at topos and look for the most contour. It's a big area and you need the elevation changes to start breaking down such a large area. Acorns usually start dropping about the time of the opener.
Second option would be around Halloween, and look for funnels/points leading into swamps. Deer numbers are down, wolf and bear numbers are up, and baiting is rampant. If you see any trucks parked on the road, keep going cause he's baiting and those deer aren't going to have normal movement.
My favorite big woods areas are where you see a wade able stream closer to a road. The higher ground on the other side will hold deer. I used to hike way back in, but I don't know if its the wolf pressure or the frequency of bait, but I find more deer sign these days closer to the roads.
I'm no expert, but grew up here hunting northern wisconsin. It's tough hunting, but if you get one you earned it!
Good luck.
