The famous New York City author, artist, and explorer Julia Solis calls this book “An important and fascinating contribution to the literature of the underground.”
New York Times best-selling author Steve Thayer asserts that “Subterranean Twin Cities is a treasure—a book for the Tom Sawyer in all of us. Greg Brick is one of those few persons with the unique talent to write expertly about his adventures, bringing readers along with him on hands and knees.”
The British caver Chris Howes, a world authority on the history of subterranean photography, praises the book: "Cavers and mine explorers will enjoy Subterranean Twin Cities andits wry humor. Don't worry that these might be two cities you nevervisit; it's a damn fun read. And you never know, as told by Greg: atleast one of the legendary tunnels has already attracted international visitors."
