I miss the smoke we had when we went to indoor weddings. As a kid, the smoke would be this high cloud just out of reach, obscuring the other end of the room where the adults were talking. The tables with the thickest smoke were where the men sat in intellectual poses, discussing heavily politics. It gave an air of grandeur to it, and when the disco lights would turn, they'd light up the smoke clouds to give off a pink/red thunder vibe.
Yeah sure, we have smoke machines now, but it typically hugs your knees and doesn't rise much, giving off a different look. It also doesn't seem much fun for kids, who I guess just see it as eye-level fog.
