LAS VEGAS -- Several more Las Vegas Strip properties will now to cater to pooches which means pet owners don't need to leave their dogs at home.

LAS VEGAS -- Part of the Las Vegas Strip was shut down Thursday morning after a sulfuric acid spill happened  front of the Wynn Resort & Casino.

Police have reopened southbound lanes and one northbound lane. They say the other northbound lanes may remain closed much of the day to clean up the spill.

The Strip was closed from Spring Mountain Rd. to Convention Center Dr. causing major traffic backups on Spring Mountain Rd. and Paradise Rd.

The spill occurred around 8 a.m. when a contractor was attempting to fill tanks for the resorts pools and water features. About 200 gallons of the acid leaked when the pipe broke. The spill happened outside the resort property near the front entrance of the Wynn.

One person, who slipped and fell in the substance, was transported to Sunrise Hospital. His condition is stable. Another person who got the acid on their clothing was also transported.

LAS VEGAS -- It's meant to improve people's health but a smoking ban at McCarran International Airport enacted about four years ago is one of the reasons gaming revenues are down.

Airport officials say gaming revenues are down about $5 million from last year. They say there are three main factors for that and the smoking ban is one of them. The Clean Air Act was passed by Nevada voters in 2006 banning smoking basically anywhere except casinos, bars that don't serve food, and brothels.

As a result, McCarran got rid of its indoor smoking areas so now smokers head outside for a smoke instead of staying inside and playing the machines.

"It's time to take a break, gather my thoughts," said traveler Chris Wetzel. He says lighting up and chancing his luck go hand in hand. "They've both been together forever and now because one is not allowed its obviously taken its toll."
