> "That's an example of you having to care about which city you're in." Not really. If you're worried first and foremost about common sense, then you don't need to worry about the law. Common sense would preclude discharging a firearm in any urban or suburban area, unless you are inside a commercial firing range. It doesn't matter which city you're in, because you shouldn't be doing that in any city no matter what that particular city's laws are. Even if through some oversight that city neglected to create any laws concerning discharging firearms, common sense should still prevent you from doing it. If you're on some deep rural farm and want to know whether it's legal or not to set up a private firing range, then you definitely need to consult your local law; there may be unintuitive laws about the distance you need to be from other property, roads, etc. But as far as shooting guns anywhere near a city is concerned, common sense should be enough to keep you on the safe side of the law.
