A totally dumb trad bowhunting tackle law created by people who don't know squat about archery, bowhunting, and probably too many other things in life, and yet they seem to get voted into office annually, much to smart people's dismay.
If there needs to be a minimum "hunting bow weight", it should not be the bow's labeled weight (which we all know is usually not all that accurate anyway), it should be the measured holding weight at the archer's full draw length.
Or heck, just remove the current bow's labeled weight and write on yer own - I doubt any official in the field will do more than look at the bow, let alone have the smarts or equipment or the want to check further.
