Which is a good idea. You don't want to be launching mortar class fireworks in a city setting. Although some can get away with it, like in Washington (at least the western part). From what I know most of the restrictions on fireworks is to prevent fires rather than prevent bodily harm. That's the reason why mortar-class fireworks aren't allowed in Idaho, but the funny thing is that I can go over to Wyoming and get all of the illegal fireworks that I want. Washington though, its so wet over on that western side that you don't need to worry about it as much. If you're safe with a firework, you'll be fine.
There are idiots, such as myself and my friends, who enjoy shooting each other with roman candles while wearing rain coats to prevent burns.
