Twenty years ago I worked at a place that had offices in buildings across the street from each other and had a laser network link between them in case the link through our ISP stopped working. I don't recall if we ever had to rely on it while I was working there, but I remember the guy in charge of monitoring it used to complain that it didn't work on foggy mornings. One end of the link was on the 21st floor, and we got fog at that level a lot more often at that height than at ground level.
