About 40 years ago my grandpa worked for a construction company. As they were building they learned of a wreck sitting on the land the were building on. They worked for a day or two on it but as they dug the tide just filled up the hole. They got a drill and the drill pulled up blackened wood. And bits of metal. He told this story as long as I can remember. It is known who's treasure it was and there's roughly a half a million gold coins in the ship. Problem is u huge company owns the land. I fear it will sit forever I would love to see it unearthed in my lifetime. Is anything possible to help get this done?
