I remember this happening. I was watching the local news when they reported a treasure chest being found downtown. They had video of kids and businessmen scooping up dirt with their hands looking for coins. I begged my mother to drive over there (I was 7or 8 at the time), and she took me over there. By the time we got there, the site was off limits.
Makes me want to buy a boat put on some pirate clothes and sail around looking for lost wrecks for treasure.
