Yeah, the regulations can get complicated, and I haven't even checked the Federal Hunting regs for that area yet. That's important because most of SE Alaska is part of the Tongass National Forest, and the toothpick cops love to make up their own rules.
The cabin we were talking about about, Beecher Pass Cabin is located on Woewodski Island. Looking at the map for DL030, Woewodski Island is not part of that hunt. You can stay there, but you can't hunt black bear on Woewodski with the DL030 permit.
Go to this website...
http://www.adfg.alaska.gov/index.cfm?adfg=huntingmaps.byhuntnumber...and type in your permit number DL030 and it will come up with a page which has two maps of the exact hunting area for that permit. To hunt Woewodski, you need DL031.
You are better off with your permit to hunt Kupreanof Island. There's no way Woewodski has enough quality black bear for 4 tags to fill.
I see there are at least 4 other cabin located in Kah Sheets Bay which are actually in your permit area. Most of the require a serious high tide to access though. But if you can research the salmon runs in the rivers nearby those cabins, you might find one that will work for you.
Another route to take is to hunt the road system out of Kake, and hike into whatever salmon streams you can access everyday. You could camp, or return to Kake each night.
If you can contact JJHack on this forum, he'd be a good source of information too.
He told us about seeing a brown bear on Kupreanof years ago. They're not suppose to be there, but someone forgot that bear can swim. SE Alaska brown bears can be very dark colored, and mistaken for black bears if not observed carefully.
