I’m going through photos for some things I am working on . . . more details later, but I’m excited to see the end results! Gary likes to get photos of funny or interesting signs, and this is one from Italy. What do you think it means? Stairs are wet, steep, slippery?

probably means they’re steep, and slippery when wet! : D
sign is used when stairs, corridors, etc are whipped with wet cloth. In Slovenia we have a lot of signs like that.
