How To Shit In the Woods, by Kathleen Meyer
Reader Review: "I love the humorous, down to earth way this subject is approached. Originally I bought this book because the title and the picture on the cover made me chuckle. I've had it in my possession for at least five years. Then a little over a week ago, I decided to read it. To my surprise, I learned that this is a serious book with important information to help a would be hiker stay healthy and leave the environment no worse for the wear."
