This riverboat is in Dubuque, right where Iowa, Illinois and Wisconsin meet on the Mississippi. Their old boat was so cramped you could barely squeeze your way between the machines. The current boat is a lot roomier. The Slot cards went from the Diamond Club Card, to Diamond Jo Slot Club, to Diamond Jo Player's Club. The Platinum version of the third type, as shown below, has a "55 & More" seniors sticker that they still use today. All of these cards are pretty old and hard to get. I have a couple of the green type three cards for trade for obsolete cards.
