Started kind of small when fireworks became legal in Michigan, the show gets a bit bigger every year. My in-laws have a cabin in northern Michigan on a couple hundred acre lake. They all chip in and my wife and I purchase all the fireworks and I do the show. A bit over 2 grand worth this year. The neighbors all love it and we have a bunch of boats lined up out on the lake to watch. Lasts about 40-45 minutes. Bought a remote control ignition system and if it works right I'll get to sit up on the hill pushing buttons and watching this year instead of being right under them with a propane torch.
