What I know about grizzly bears I learned from watching the Nature channel back in undergrad, so feel free to add on. Grizzly bears are big, strong, and mostly like to fish, mate, and roam around when they're not hibernating. They're not aggressive, exactly, but if they want something it can be pretty difficult to tell them otherwise.
