The problem with party hunting is in the licensing structure in North Dakota. This has been explained countless times but apparently some people just don't get it.
If party hunting were allowed, some deer hunters would put in applications for their wives, daughters, grandmas, aunts, uncles and so forth. The result would mean grandma, who doesn't hunt and will sit in a pickup reading a romance novel, will draw a buck tag, while the dedicated deer hunter will be sitting at home having failed to draw a tag. It's really that simple.
Also, it is illegal to party hunt in almost every state in the west. It leads to abuse and unethical hunting practices. Yes, some do it in North Dakota, but that isn't sufficient reason to make it legal.
