Query: Wonderful & emotional!

I read this book on a camping trip in the Kananaskis. I looked forward to my lunch breaks on a rock by a lake or at the top of a rock scree so that I could continue my reading.Marty takes you with him as he explores and cares for his territory. He teaches you what he can, but the lessons only sneak up on you...like the time I rounded a corner on a narrow trail and found myself face to face with a moose and her calf...'never get between a grizzly and her cub, that's when you're in trouble'...the lesson seemed applicable in this case, so I slowly made my way past rather than reaching for my camera.I find I value the parks much more after reading Marty's book and hope for their future.
