"One of the most interesting sites I have seen is stangrist.com Adventures Into The Unknown! Stan has an extensive web site about his own personal adventures and explorations: discovering lost civilizations, gold prospecting, diamonds, metal detecting, treasure hunting, and much more. He also has a library about explorers and fascinating subjects like subterranean tunnel systems, and cryptozoology.
Treasure hunters, Explorers and Prospectors will find his site a gold mine of information and his Training Course is top notch, great reading and inspirational. I highly recommend it. A 100% unconditional guarantee is included. Check it out for yourself:
