Top secret tourism by Harry L Helms( Book )

"Here is the unseen America of government facilities and installations protected by a wall of secrecy, deception, and misinformation. It includes huge, isolated areas (some larger than the states of Connecticut and Rhode Island), along with innocuous office buildings located in the middle of major cities. This other America has an enormous impact on your life, but you probably have little idea of its extent, scope, and power. This book invites you to visit this top-secret America. Listings are by state, and each facility/site entry gives its history, discusses the activities carried on there, explores various rumors, and provides maps and directions to every location. Author Harry Helms visited and photographed a number of sites in this book. None of the intelligence here was taken from classified sources; everything was on the public record and obtained by patient digging. Since the 9/11 attacks, much of this information was removed from public dissemination. To those who think a book like this discloses vital government secrets, Helms says: Get real. If I can find this stuff out, the Russians, Chinese, and various terrorist groups also found it out a long time before I did. Adventurous travelers and truth-seekers will want to know how to navigate within top-secret America."--Publisher's description
