When it comes to swimming holes, we can define pros in a variety of ways. You may have already purchased this book's predecessor, Swimming Holes of California, and visited many, if not all, of its swimming holes. This makes you a pro based on experience. Another type of pro seeks out swimming holes with cliffs for jumping, while other pros like to backpack miles into the wilderness in search of freedom and solitude. Whether you enjoy one or all of the above activities, we've designed this book to meet your needs. No matter which pro option you pursue, this book will have something for you.
