I just got back from a week on Plum Lake in Vilas. Hardly ran into anybody. Also, there are so many lakes in Vilas that are lucky if they see a boat a week.
Lost Lake, Mann Lake, Little John, all stacked with fish and almost no pressure. Ballard Lake, Razorback, Hobo, the list goes on...
Of course there are lakes that are heavy utilized like Lake Minocqua, but even then I don't think they see the pressure that some of the lakes in SE Wisconsin get i.e. Delevan, Lake Geneva, etc.
There are Lakes in Vilas County such as Aurora Lake that I wonder if anybody has fished it all year (other than myself of course.) I've fished Aurora for 15 years, and I have never saw another boat. Vilas has so many remote lakes, great snowmobile trails, beautiful parks, great bike trails, it is truly hard to beat.
