Did a hunt with Jake Jefferson of Black River Hunting Camps in Alaska last fall. Very happy with his experience, attitude and the amount of effort he puts into the hunt. The area (north of Talkeetna, west of Mount McKinnley) is breath-taking.
Jake's hunts are pretty basic in terms of creature comforts -- it's just you, the guide, and a tent out in the middle of absolutely nowhere. The degree to which you'll enjoy the experience is completely dependent on the amount of conditioning you've done in the months prior -- it's big, open country that's not nearly as gentle as it looks from the air.
Bottom line, though, is that I would definitely hunt with Jake again. We'll just need to hunt something other than grizzly, as we managed to tag a beautiful one on the afternoon of the first day! :-)
