Lots of good advice here. The only thing I would add is that the hunter success for archery elk is fairly low - and the odds are you won't get one. You will almost certainly see and hear elk. Pretty likely you will evenget within shooting range. Try to enjoy the whole experience of the thing. If you actually get one, it's a "cup runneth over" experience.

ALso, you can get an either sex license; and subsequently get an anterless license as well. Would allow you to get lucky and kill a cow the first day - and keep on hunting. Kinda stinks to sit in camp for ten days if you tag out the first day. Bring a fishing pole otherwise.
