Funny how you always redirect everything back to poor Steve
You are correct, grizzlies are nastier characters than black bears, but I don't think I want to go up against either one. Grizzly/human encounters are much more rare, probably due to a smaller population and like you said, they generally don't like encountering humans. Unless you get between Mom and her cubs, you should be fine . Also, Grizzly diet consists of mainly berries, I don't believe goat is a staple in their diet.
If your lucky, while going through BC, you may get to see a Spirit Bear on your travels, though most likely not.
Hmmm, Black bears, Grizzly Bears, Kodiak Bears, Spirit Bears and possibly Polar Bears. Maybe you should be concerned .

P.S. If your entering Canada, leave your gun at home. They aren't too happy to see them come across the border without the proper permits and licenses.
