Each individual US state is different. I live in the Northeastern section. Most of the states my way are pretty strict with fireworks, only letting a few small things be legal (sparklers, small firecrackers) whereas a lot of Southern states have less restrictions regarding fireworks. A lot of people will buy the really big and dangerous ones down south and transport them across state lines to set off up here. They're illegal, but good luck enforcing it, especially this time of year.
