Thumper, For each letter of the main word, you write another word that has something to do with the main word. In this case the main word is campground. Azoyizes used the "c", then I used the "a", the next person uses the "m" & so on. Then the one who uses the last letter (in this case, "d") also puts a new main word.
I'll use the "m".
