Fireworks are illegal for laypeople in Illinois. You can't buy anything other than smoke bombs and sparklers. A lot of towns and cities do their own big displays, though.
We live in an unincorporated area outside Chicago. The village we are affiliated with doesn't do a firework display, but other closer towns do. None have cancelled yet. There was only one year they canceled due to dry weather, a few years ago. But, they have threatened to a number of times.
When I was a kid this never happened
Climate Change is real and we're seeing it increase every day.
