Query: A Waste of Space in my Suitcase

This book didn't help us at all because it did not have much information. For example, the trail descriptions are very short, typically only one paragraph and many only one sentence! Much better books are AN OUTDOOR FAMILY GUIDE TO YELLOWSTONE AND GRAND TETON NATIONAL PARKS by LISA GOLLIN EVANS (for detailed descriptions of many great hikes) and FROMMER'S YELLOWSTONE AND GRAND TETON NATIONAL PARKS (good for planning your trip and detailed descriptions of some hikes).
