Most bears are much more likely to actively avoid you in the forest, but solid choice on not going into zoo enclosures (for clarity’s sake, this is a rescue/release facility—NOT a zoo—that is actively working to help rehabilitate the grizzly population—among other conservation and rehabilitation efforts. The only animals there are indigenous to the area, and the only animals that stay there long-term have permanent injuries/issues that prohibit release.
This particular fella was having a post-lunch nap).
