Don't forget to use a cow call. If you spot a herd of cows and can get set up near them, a "lost cow" cow call can geta cow in close enough for a shot.Mostly works just on the cows orvery young bulls. Them bachlors herds are hardto sneak up on like a cow herd, but if your lucky to spot a sinlge bull you may get a shot.
I've hunted cows that seen me, and just kept a distance (just out of bow range) from me and moved off. If you have a buddy hunting with you, you mayhave one of you set up somewhere and the other try to "push" the elk past the shooter.
I liked the idea of a hay stack too
If you have a rancher in your area with nusance elk, he may not mind you camping out on his hay stack.
