Our once-pristine wildlands are threatened by ever increasing problems of pollution.  Since its first publication in 1989, How To Shit In The Woods has been adopted by outdoor enthusiasts everywhere as part of the solution.  In this updated edition, outdoorswoman Kathleen Meyer reviews the newly available portable potties, with special attention to individual trekkers in an all new chapter, “Plight of the Solo Poop Packer.”  Other topics include: the growing array of travelers’ field water disinfecting systems, Giardia contamination and the now infamous critter Cryptosporidium, crotch-accessible clothing for women, and a fresh batch of “worst experience” stories, all peppered with irreverent musings.  For the purist, there are more wise t.p.-less techniques from the Old World.
