Jim and Greg, I live about a mile away from Ameristar Casino in St. Charles. It opened as Casino St. Charles. Shortly thereafter it changed it's name to Station Casino St. Charles. In August of 2002, Ameristar opened a new casino on the same property, although they had purchased the casino a year or so before that. It was never called Riverfront Station to the best of my recollection. I think there have only been two chip issues. Hope this helps.
