Never been there but I would check with your local sporting goods store. They should be able to point you in a direction. Talk to the locals and see what they do for archery. Branch out and talk talk talk and you shall get some good answers to get you where you are wanting to get
I was talking to my buddy who lives just outside of Anchorage and he said that any of the local sporting good stores should be able to do it. He also said alot of people take their stuff to the mom and pop stores. He said they tend to have a little more customer service. He was unsure of any clubs but believes that there should be as he said "It is Alaska, if we don't have a club I would be damn suprised.."
I think Fire has the right idea about talking to the locals they are usually a wealth of knowledge.
I remember a show on the American Sportsman back in the 60's that had Fred Bear on it hunting a Brown Bear with his long bow. He said that even being close enough to the bear to shoot it with an arrow didn't scare him since once the arrow is released the bear wouldn't know where it came from like a shot from a rifle. All the bear would notice is that something bit him and would react it that. Then on the show when he arrowed one that is exactly what happened. The bear turned and bit at the arrow and then ran off and died.
Now as far as hunting them I am planning another Alaskan hunt or one in BC for a mountain Grizzly with a pistole. Just call me crazy.
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...
