Everything that Curly said, and I would add a predator call. Even if you don't set up and call it can come in handy. Say you see a bear just as it is heading into the thick stuff or over a ridge, you can at least call a couple times to see if you can get the shot. Another good time is when you are getting ready to leave a feeding area. Call for a few minutes before you leave. You never know what will show.
