A great book if you ever find yourself walking along San Francisco's Ocean Beach, the westernmost point of the city that meets the Pacific Ocean, this would be a great companion book to have with you. For anyone else, it's still a cute collection of what you'll find in nature when in the area. From understanding how basic currents work, what some of the animals and plants you'll find are, and what they look like, this book has got it all. The illustrations give this book a sort of charm that feels native to San Francisco.
If you want to learn a little bit more about what you'll find in Ocean Beach, this is a fun diversion before you head out there yourself.
