Why would you NOT wear it? If you are in the woods (during deer rifle season), it is for your safety. If you do not wear it, you are not concerned for your safety. That's reckless.
I don't wear it if I can avoid it during deer season.
Your finger should NEVER be on the trigger until you have 100 % identified your target and made the decision to kill it.
There are NO ACCIDENTS. Only fools or people using that excuse to get away with murder.
