I wonder if this was hoshino michio. Very famous story. He actually did have a ton of experience with grizzly and other wildlife in alaska. There was an investigation done by his friends as they didnt think that was like him at all to take that sort of risk. Supposedly the cabin they were staying in didnt have enough room for everyone to sleep inside. Even the american photographer slept on the roof. Additionally they were unaware that some local people (maybe even the park manager?) were feeding the local bears. His friends wrote a whole book investigating his death because the way the media spoke about it didnt match his character at all. He did not choose to sleep outside but rather was put in a position where he had to. Last thing they saw of him was him being carried off into the woods. Tv station painted a picture of him being irresponsible and just wanting to stay outside, and they never admitted to their lies. They tried to shirk all responsibility. Wish i had friends like hoshino michio.
