OK, I'm getting the hang of this: a brown bear isn't brown; a smaller bear isn't a Grizzly unless it's a small one; if a bear approaches lie face down and the bear will leave you alone - unless it is hungry in which case it is then a bit late for Plan B.
Bears can outrun you and climb trees, so you bear escape options are limited. . . Oh yes and you can tell the dangerous bears by looking at their paws. That's easy then! Hmm.
A moose on the other hand. . . .
