It really does not matter where you decide to go.If there are elk in it, it will be crowded..Pick a unit that you can spend the most time in..Scouting is probably the most important..All the maps/internet information are outdated.They are cutting lots of trees because of the "$hortage" and those beautiful timbered basins might be giant clearcuts...Those giant clearcuts might be thick brushy draws, or giant bare ground wastelands (sprayed).Nothing beats boots on the ground..90% of the animals are harvested by the same 10% of the hunters because they know where the animals are before they park their truck..First couple days of season, the elk will be following some old cow that has survived 8+ years because she has learned how to avoid hunters..Knowing those spots that they hide in is "the honey hole" nobody wants to give up because it took them years to figure out...Every unit has elk.In my experience, every major drainage has a herd somewhere in it.It's figuring out where they are that's important..Scout an area and learn the road system.Nothing sucks more than finding an empty gate and finding out that it is empty because it goes nowhere, or there is easier access from a different spot and 6 other guys are coming in from the other side after you walked 5 miles to get there..But, some of those ignored access roads might be good places to go because they don't get the pressure...Elk are where you find them..Sometimes they are not in a spot, but when you go back in a few days....That's why scouting, and choosing a specific unit to learn is important..1st year, you learn an area.2 year, you go back to those areas that look promising.3rd year, you start to figure out patterns.4th-6th year you have your "honey holes"7+ you start being consistent in finding/killing them....And you have now met several other hunters you see every year..Welcome to the unit!.Now you tell everyone that it sucks, there are not any elk there, etc...
Bull only units might have fewer hunters, because one of the attractions is the ability to harvest a cow, however herd reduction has devastated the populations..WDFW has spent more time worried about managing hunters than animals that they have forgotten about "resource allocation" and herd management..The "Any elk" and 3pt-antlerless units are getting wiped out, the best areas are either pay-to-play, or permit only..$$.
Not much knowledge on the other units but I've spent most my life in the 572. Its becoming tougher each year due to the amount of campers, bear grass/mushroom pickers, bikers, hikers, spalunkers and various other people up there. There is elk but it's popular and as a result the elk are skittish.
