There are no signs in Mexico, at least none that aren’t out of date or unintentionally funny. My personal favorite was the sign on Chacala beach that said no mascots were allowed. (Mascota is the word for pet in Spanish.)
It isn’t easy for someone like me to get accustomed to a place where you can’t find the information you need in writing. I’ve been known to read software manuals cover to cover. When I want to know something, I go on the internet or buy a book. I expect pamphlets, signs, and lots of fine print.
