Bears know how to do it, but what about the rest of us? More and more people head for the hills without thinking about poo – so piles of pink tissue paper and worse decorate what should be wild landscapes. But there are ways to shit in the woods (and hills, deserts and riverbanks) without damage. Kathleen Meyer has appropriate suggestions in How to Shit in the Woods (second edition, Ten Speed Press, Berkeley California £4.99/$9.95 ISBN 0 89815 627 0) including how to take it with you, together with horribly funny anecdotes and a fascinating digression on appropriate language.
