...a new GPS device enables authorities to remotely control a bus -- slowing it down to 5 mph and preventing it from restarting once it has stopped. The device has been installed on thousands of local commuter and tourist buses.

The technology is designed to prevent a terrorist from ramming a bus filled with people and explosives into buildings or tunnels.

Private bus companies have received millions of dollars from the Department of Homeland Security for the security systems. It costs $1,500 to equip each bus, with $50-per-bus monthly maintenance costs.

Gray Line double-decker tourist buses and Coach USA have spent hundreds of thousands of dollars in federal funds to install 3,000 devices. After receiving a $124,000 federal grant, DeCamp Bus Lines is installing the device on its 80 commuter buses, which travel routes from northern New Jersey to the Port Authority Bus Terminal in Midtown.

New Jersey Transit is currently in the process of equipping all of its roughly 3,000 buses with the technology. NJ Transit Chief of Police Joseph Bober said: "This enhanced technology helps us protect our bus drivers and customers. It's another proactive tool to protect our property, employees and customers."

Why is there no sports book in McCarran Airport in Vegas? The place is full of slot machines. Isn't a sports book the perfect gambling option for someone on a layover who doesn't want to play slots? -- Jeff, Valparaiso, Ind.

SG: You're making too much sense. McCarran needs a sports book, blackjack and craps, and it needs an area where you can walk around in a black leather jacket screaming "Serrano's got the disks! Serrano's got the disks!" without airport security tackling you.

There is no question you could charge people to reenact Serrano's got the disks.
