Australia is almost as big as the USA... USA = 9,629,091 square kilometers, 6.4% of the earth's area... Australia = 7,692,024 square kilometers, 5.2% of the earth's area... there are 13 casinos in all of Australia... how many casinos in the USA?

Interesting question and not as easy to answer as I thought it would be... wiki.answers says around 475 casinos... while an article in wikipedia references 1500 casinos, which I assume includes legal cardrooms. Anyone have a more exact count?
