Haystack by Bonnie and Arthur Geisert

This is a nonfic book about the life of a haystack.  They cut the grass and put it in a big pile.  Then they stomp it down to pack it.  Thunder is a threat because it can burn down the hay.  The hay is used to feed cows and pigs during the winter.  By the end, all that's left is poo which they use to fertilize more hay.  This book was fascinating!
