LAS VEGAS (AP) — Nevada casino winnings were up 3.6 percent last month after Las Vegas Strip revenues posted a healthy gain over last year, state officials said on Thursday. The state's casinos won nearly $949 million in September, a bit shy of the psychologically important $1 billion mark the state hit in July, according to the Nevada Gaming Control Board. Only two of the state's gambling regions are down so far this year compared to last — the heavyweight Las Vegas Strip, which is down 0.3 percent, and northern Nevada's Carson Valley, which is down 1.3 percent.
