Hi Treb! I actually live and hunt in Alaska (for nearly 40 years).
Brown's suggestion about McCann and buying his book was a good idea to introduce the state. McCann lives in Fairbanks, and that's in the central part of the state. Some of the best grouse-sharptail, and ruff grouse hunting is north of the Alaska Range and along the Yukon and Tanana Rivers. Ptarmigan are ubiquitous but it takes local knowledge to find huntable area and populations. Alaska has a lot of state and federal huntable land but way most of it is off the road system. Most of the land along many of the roads is private. Lots of land (44 million acres!) owned by Alaska natives. They typically DO NOT allow public hunting on their land.
There is also a long north country waterfowl season and great hunting for everything from ducks to cranes either along waterways or in some areas, agricultural land.
Some friends outfit a "cast and blast" hunt for ptarmigan and trout/dolly varden. Usually floating Alaskan rivers. Contact me for further info. It would be possible the get a "McNab" in Alaska...shoot a caribou, a ptarmigan and catch a char in the same day on a river in Brooks Range.
If you like, email me with specific questions and I will help as much as possible.
Cheers!
Mike
