A short guide to national parks and other natural attractions in the United States, all the most interesting things that you can see while traveling by car between the shores of two great oceans. We traveled 43,000 miles (68,800 km) across forty-five states to compile and convey to you the impression of these places. But you will find not only personal experience on the pages of this book, but also factual material based primarily on data from the US National Park Service.
