You're not going to find any support for ordinances here regarding the use of firearms because it's an activity that many here enjoy or participate in.
I understand and I agree...I don't want people telling me I can't target shoot or hunt on my own property either. It is sad that regulation should even have to be discussed but when their behavior impacts others' safety, how do you do something about it if nobody will tell them to stop until someone gets shot? It is just a sad situation. I'd hate to see a neighbor pay the ultimate price for his stupidity. I don't think requiring a backstop should be such a bad thing? I don't know a single responsible gun owner that would object to that requirement.
