90% of the hunt unit lies in the checkerboard land pattern and you will need some sort of permission from the private land-owners to access it. This used to be a common and pretty easy process for a significant portion of the unit, but unfortunately the situation has changed dramatically from 15 or even 10 years ago, and almost all of that country is now off limits to all but guided hunts (ranches are leased, or in one case, allows no hunting at all.) Although the internet and other hunt "advise" services tend to ignore it,there is a damn good reason that the WGFD warns potential applicants when a unit has extremely limited public access, and this unit qualifies. Much of the recommendations for units like this come from a perspective of a guided hunt, or very limited experience and exposure to the area. Probably not what you are looking to hear, but realistic.
Finding out what areas are accessible to the average public land hunter will require looking at the land status maps and determining where the county and limited BLM roads lie. You're looking at more "fringe" type country, rather than the heart of the unit. You can get an idea of what terrain and habitat you are interested in hunting within that country by putting some miles on the pickup and boot leather good luck!
