 Fireworks are banned on most public lands. That includes state parks in most of our United States, as well as Forest Service lands, Bureau of Land Management lands, and national parks. So don't light off fireworks at those places. If you are lighting off fireworks, make sure you're doing so in a place where you're not going to catch anything on fire. Make sure that you put those fireworks in a bucket of water after they've gone off. And if you've got any duds, do the same thing with those.
