What would be a fun project is traveling the world, and seeing everything in this book like it was one giant to-do list. We are, however, not able to do that. I have flipped through this book, and was dismayed by how not able to do any of these things we are. I don't know who this book was written for. If you live near these places, you have probably been there. If you don't, too bad. Also, none of them seem like must-see-before-you-grow-up places, as the title would imply. They include places like Machu Picchu, The Great Wall of China, and Mt. Rushmore. They would be cool to see at any age, and you might appreciate them more when you have the perspective of years. I know my kids would love to travel more, but we will not be using this book as a guide when we do. Better to get a guide of the location you're actually traveling to.
