I don't know how many workers get involved in this "treasure hunt", but looking at the picture seems to be a monster number of chips... I can bet someone has gone out from the "site" with as many as he can carry (and if he had a pickup...).
If this chips were sent here back from Atlantic City to be destroyed i guess this hole is only a small part... and surely the guys got more chips than what we see in the picture.
Well i'm sorry for all the people who's paying $20-25 each now... they are worthless...
