An acronym is an abbreviation formed from the initial components in a phrase or a word (i.e. tftc). In this series it is the word. Each of the caches placed in this series will be with a sign that has a word(s) on it. The acronym I have used will be the only thing in the short description, that will be your clue for the right sign. However, the sign could have more than one word or there could be several signs.
Your Responsibility (which is optional)- When posting you have "found it", Please put your own acronym in the comments for the word or one of the words on the sign.
BE CREATIVE (but keep it clean) and have fun.
