CONCORD, NC (WBTV)- Charlotte's bid to win a contract to host ESPN's Summer X Games is facing a critical hurdle this week. Wednesday marks the second of two days network executives will tour the area and facilities that would host the event.

Charlotte Motor Speedway and the zMax Dragway would be two venues used for the event.

On Tuesday, WBTV was there as the Speedway enlisted the help of a NASCAR driver AND X-games gold medalist, Travis Pastrana. Pastrana took ESPN officials for a whirl around the race track.

In April, the X Games announced that Charlotte was among the four finalist cities competing to earn three-year contracts to host the North American summer stop on the X Games global tour beginning in 2014.

CONCORD, NC (WBTV)- It's a dirty secret that threatens to cause homeowners a messy, smelly, and expensive problem. All over the country, and right here in the Carolinas, city and water treatment officials say those fresh wipes that are supposed to be flushable, are causing sewer systems to back up, sometimes in people's homes.

Concord, like most cities, uses a truck like this to clear clogged sewer lines, and lately, those clogs are caused by these. The package says they are flushable and that they are sewer and septic safe, Gary Fritz says look at the evidence.

"They say they're biodegradable, they're flushable, but they're not dissolvable," Fritz told WBTV. "They're biodegrading, but after four months, and it doesn't stay in the sewer system for four months."

He's kept a flushable wipe in a jar for months, along with other things that end up in the toilet, to show the difference.

The Jay M. Robinson High School is holding a fundraiser for its Athletic Program this weekend.

Rather than donating money, participants have the opportunity to give ten minutes of their time.

A Charlotte dealership is helping the High School raise money, by offering free test drives of a new Lincoln on the school's campus in Concord.

Each test drive brings the Athletic Program one step closer to its $8000 goal. Volunteers who test-drive a second vehicle will help raise an additional $20.

Car enthusiasts can ride in style at the Jay M. Robinson High School, located at 300 Pitts School Road SW in Concord, Saturday June 1, from 10 a.m. until 4 p.m.

The cost is free, and the Test Drive is open to ages 18 and up. Must have a valid driver's license. Online registration is required.
