Chuck, LOTS of Centennial chips...most are gone already though...Riviera , Texas Station, Fiesta, Boulder Station, Palace Station, both Arizona Charlie's, Santa Fe Station, Green Valley Ranch, Circus Circus, Slots-A-Fun, Rio, Stratosphere, and I'm sure I've missed some . I've got all except the Stratosphere and Rio (so far), and will bring them for traders to the convention. I'm sure there's more still coming!
