Yeah; two things: one, bears are no big deal if they’re accustomed to humans and humans are accustomed to them. Two, Texadans aren’t accustomed to grizzly bears; grizzlies don’t come to the islands. Since you need to know how to behave around grizzlies for it to be safe to be around them, this could end badly eventually.
