Help in Idaho unit 41

I Drew an Idaho unit 41 late season tag. I know there are some big bucks in there. I hunted it three years ago with not the success I had hoped for. Has anyone hunted this unit before succesfully. I would appreciate any comments or hints. It is a huge unit typical of sourthern Idaho high desert. Very few trees with lots of dry washes and few river canyons. I intend to scout several times before the season. Any areas I should focus my scouting on? E-mail me to discuss specifics, or post a reply, thanks fellers.
