Folks in Chicago are WALKING on it…..which is asking for death, ’cause it varies in thickness from feet to inches (or less)… it is often not clear hard ice, but more like sorta compacted snow. And you can’t tell if it’s gonna hold your weight until you stand on it, after which it is generally too late.
Darwin at work here, folks. I know of several times in my lifetime that people have died from falling through the ice over Lake Michigan. Pretty stupid behavior. Rescue crews should not put their lives in danger doing any sort of rescue or recovery of people stupid enough to do this.
