Wow! That is pretty impressive! The state I live in just recently started allowing some of the bigger fireworks. Up until a year or two ago they had been banned. They have some new rules though like they can only be shot off on the holiday, the day before and the day after. Most people tend to stick to those rules. My brother in a law used to work for a fireworks supplier so he was able to get his hands on some of the bigger stuff back when they were banned. He was moving one in the warehouse one day and it went off in his hands because someone thought it was a dud and left an e-match in it. Thankfully he made a career change shortly after that!
