I did not hunt 24 last year but have hunted that area for several years and have had very good luck. I have bow, muzzle loader and rifle hunted in 12/24 with good luck in all seasons. It will take you at least one or two preference points to draw an archery tag in 12/24 so hope you have them. Not sure if you looked up the stats for last year but here is some info. You can get all this from the DOW (or whatever they are called now) site too.
In 2011 there were 630 archery tags available with 1015 first choice applicants. Of those who got tags 200 were non residents. I would guess 2012 will be very similar.
2011 harvest rate info is not out but in 2010 the success rate was 14% in unit 24 for archery.
Hope this helps but if you have more questions let me know.
Bring them in on a string. I love this term, if you want to be successful on calling in Elk, try not to just sound like the other caller. We all laugh at each other when we are practicing Elk calling at home or while camping. When I first started calling in Elk, I had no idea what i was doing and it's funny how many I could call in. The biggest Bull that I have called in to date was actually my first. I was making cow calls and screwing it up big time. But it's obvious I didn't screw up...
