Spaceflight life support and biospherics Book

I like to buy a book when we take trips. I bought this little volume about 15 years ago when we visited Timpanogos Cave. With simple pictures and text, this book shows you that you can read stories in your environment, just like you can read books! For many years I've helped my children discover and read the many wonderful stories that can be found in nature. This book was a catalyst for that.

I had just reread this book last week and while walking down the street a few days ago, was able to help a few neighbor children discover the "story" of pheasant tracks.
