This is a book that will fit handily in any saddlebag, in any creel, in any backpack, in any river runner's ammo can -- and in any picnickers' picnic basket. No good American should ever go into the woods again without this book and, for example, a hammer and a few pounds of 60-penny nails. Spike a few trees now and then whenever you enter an area condemned to chain saw massacre...you won't hurt the trees; they'll be grateful for the protection; and you may save the forest.
