Like they said. Hunt where the elk are. Sounds simple but if you're running around in the woods where elk don't live you won't find them. Look for droppings and hoof-prints and try to gage how fresh they are. An active elk area will have lots of fresh sign and probalby some broken branches where the big bulls are still tearing up stuff.

Also, try to hunt with your ears. You can generally hear elk walking around if you're quiet and still. Also they'll cow call a bit too if they are relaxed. I'd try to get out to an area in the dark before first light and just sit as quiet as you can to see if you hear any. If that doesn't work then try some soft cow calls or maybe a bugle if you're good at it.

One thing I've been doing a lot is watching hunting videos. After seeing how the pro's do it you'll have at least some idea what to expect. If you can find the elk, getting a cow shouldn't be too hard. Just be ready to pack a lot of really good eating meat. Good luck!
