i dont know much about 4 or 411 but unit 3 i have hunted and borders the gmu i now hunt. Definitly try and get the latest season you can, because in the late season when i hunt the elk are running everywhere(we even saw a group of over 400 last year) but when we dont draw late season we usally go 3rd and 4th its harder but the elk are still there. and there will be alot of hunting pressure in unit 3, but thats not always a bad thing.
