Providing further evidence of increasing competition from a revived Mississippi Gulf Coast, Louisiana's state-licensed casinos saw their winnings from gamblers in April drop nearly USD 9 million from the same month last year. The state's 12 riverboat casinos, Harrah's Entertainment Inc.'s downtown land casino in New Orleans and three slot machine casinos at race tracks took in a tad less than USD 205 million last month, compared with USD 213.9 million in April 2006, state police reported Wednesday.
