Guides to Cape Cod seem to be plentiful this season, and this is, perhaps, the most comprehensive for actual use as a guidebook, living up to the subtitle, The Complete Guide to Cape Cod. Imagination and originality in presenting all sorts of facts:- a brief preamble, then the towns, one by one, lists of what to see in each place, including in addition to the usual historical spots, radio stations, coast guard stations, French cable stations -- all bits of unexpected and interesting facts. Then topography, geological history, background history, architecture, gardens, flowers, trees, fish. Beaches, golf courses, neighborhood playhouses, sailing, hunting and license rules, riding, etc. Artist colonies, players, etc. How to get there, boat schedules, driving distances, places to stay, places to eat, places to shop. Summer camps for children. Shipbuilders. And so on -- covering everything you can think of, and yet not wordy or dull for a moment, nor flippant. Good reading and the sort of information that matters.
