I have to report new material about the Dubuque Greyhound Park & Casino that I have found since I posted initially last September. First of all, regarding the tan (actually they are sort of a "polished stone" look) cards, what I reported as type 1 and 2 are actually 2 and 3, as they were preceeded by a card like type 2, but with a Powercard mfg mark. And this year they have started a system of different levels for their card holders with a reddish tint Premium card and a white stone VIP card. I am also adding to this update a card from the Prairie Meadows park near Des Moines which I traded for since my first posting. There are two types of cards from this park, the other (which I don't have) being a white card with a horse logo on it.
