The Tunnels Under Our Feet

The author went on a five-year exploration to uncover the mystery of Colorado's hollow sidewalks that culminated into this entertaining and educational treasure. When you see a manhole cover with little glass discs imbedded in it, many of which have turned purple with age, you'll know you found a treasure.
