Query: Best hiking guide to MRNP

For hiking, as opposed to climbing, I thought this was a great book. It was easy to read, well-organized, and informative. It was certainly better than Ira Spring's "50 Hikes" book.The two authors spent a whole summer just hiking all over Mt. Rainier National Park, and then wrote about what they found. Entertaining and informative.
