We did things a little different this year. We didn't go to a city park to watch one show... We went to the top of a parking garage. Could literally see fireworks going off all around us, albeit close to the horizon. I am pretty sure we saw at least 6 cities' displays, plus many illegal "home grown" shows. All fireworks are illegal in St. Louis City and County unless you have a special permit, which is ONLY given to professionals. But that doesn't really stop everyone.
