In MN you can't carry a firearm while bow hunting for deer.
You can always carry a flashlight. They can be used to temporarily blind someone, or as an impact weapon. Some are better designesd for this i.e. some Surefires. I carry a yellow Surefire. Easy to find if it's dropped in the woods, and some people have issues with black things. I figure it's the least threatining. I do have other flashlight of various colors too.
