I have friends that do that too and fortunately they always invite us. Actually, they put on an amazing show that lasts for about 20 minutes and includes a wonderful finale. We meet at 6:30 and they have a "cocktail hour" with wine and beer for the adults and soda for the kids. That is followed by a BBQ dinner brought in by one of the BBQ places, and after eating and before dark we continue to socialize with the 200 or so other guests. The kids play volleyball - and sometimes the adults join in too. It is a wonderful tradition and I look forward to it every year.I have friends that do something similar every year and shoot off a couple thousand dollars worth of fire works after a big feed.
