I have visited a "reservation" called "Foxwoods" near Norwich, M.A. It is a casino like they are going out of fashion. I understand the Indian nation are allowed to run these establishments with extremely favourable taxation rates, if any. It is a superb venue with hotel, restaurants, gaming rooms and everything you would expect to find in a casino.They ship in coach loads of Chinese, 24/7, to relieve them of their dosh at games which I feel only the Chinese can understand ( all the writing around and on the table was Chinese).
Good luck to the tribes associated with these places because the money that can be earned for good causes must run into millions.
