I agree with a lot of what TrophyHunter said. All areas are going to have "a lot" of hunters. It is a matter of separating yourself from them to be successful. I have hunted for years in one of the most "crowded" units in the state, but I get off the road approximately one mile up a very steep mountain, and all of a sudden you do not see any other hunters. Amazing how that works!
No matter what unit you pick, spend a lot of time studying topos and google earth, find ways to separate yourself from other hunters (as the elk also do), and you will give yourself a good chance at being successful.
