"I found a pyramid off of Cuba and then noticed another pyramid near it and then...a sunken ship. About 15 years ago I heard about some American soldiers from a submarine going into a bar in Cuba and shooting of their mouths about an underwater ancient city they found off the coast of Cuba. They said it had hundreds of buildings and was incredibly intact. They also said they saw numerous pyramids in it. So I have been looking for this location for years. Today I actually seem to have found part of it."
