I always carry a first aid kit with me when I hunt. Mine is pretty basic, bandages, gauze, tape to put pressure on a wound, some neosporin, painkillers, etc. I've thought about including an inflatable splint or some of that quick clot type stuff, but at some point you can't carry an EMT bag everywhere you go.
What do you you carry with you when you're out hunting?
The guy getting rolled by the grizzly in Eagle River got me thinking. While he may have not been "seriously injured" that doesn't mean an encounter like that couldn't be life threatening when you're out hunting instead of in your back yard.
