Just to to the top of this BBS and click on the section titled "HARRAH'S WANT LIST" to see all the Harrah's locations and varieties. I know that Jerry and Janice O'Neal have over 800 different types of cards just in their Harrah's collection. Of course, they consider embossing a seperate type and also the different size of printing that each casino uses to print names on the cards. The possible different combinations boggles the mind. And I never thought I would ever need "Permutations and Combinations" after I left high school.
