New Hampshire does notify the public. They are the most transparent state in the union. All proposed laws and rules are published on the website. Hearings are given plenty of notice and you have plenty of time to speak and say what is on your mind. Very friendly. Not horribly formal.
NH has the 3rd largest representative body in the world. More reps than most countries. It's up to you as an adult to keep yourself informed. They aren't allowed to hit you in the head with it.
and a few other common landscape plants are also illegal. You can often spot them growing on state and federal building lawns.
