Your whole site appears very legit, but how do we know its ACTUALLY 100% TRUE?
I feel like I would have heard/read something on the news about people finding the Beale Vault, right?
Also, I first heard about this by reading an article on AOL news a month ago about burried treasure that has not been found. Maybe they just don't have their facts right? Or technically, it hasn't been found? Just the site was found.
What other text did you use also by the way to figure out the first cypher?
