Lector caveat: The material in the links below spans the gamut in believability from the factual, and demonstrably true, to the scarcely credible, if not downright incredible. That is to say, not every word in every one of these links is necessarily true. In this world, there are hard facts and there are also flights of fancy. You, the reader, must exercise your humble faculties of discernment and God-given horse sense to carefully sift fact from fable! 'Nuff said. Let's go underground.
