You are the best....I knew there had to be other series that are not in the guide. I think I may have at lease two more different series than the ones in the Chip Guide. Now, should I submit this one on the basis of what records Mr. Roulette has to say. He said others have these series chip but have not submitted them. I will send to the guide and maybe others will fill in the gap in Harrah's Marina history. I owe you a cup of tea my friend and might spike it with a little eye-opening spirit. Thanks for sharing. You are the real, "Mr. Roulette"
