Bikers ride for a cause during 'Arizona Bike Week'

At first glance, bikers can be an intimidating crowd, but many of these "ride or die" bike lovers have a softer side, and they hit the road for a cause.

Like Tracy Mueller, who's been riding for 17 years. She says her husband, Gary, couldn't make it today because of his recent prostate cancer diagnosis.

"The sad thing is that we were here last year to go on this charity run and who knew that a year later we'd be in this place," she said.

That's why during "Arizona Bike Week," causes close to the heart are recognized, like "Peace Out Prostate Cancer." Tracy says she's dedicated to spreading awareness for her husband's sake.

"He was lucky, we got tested early and he's in stage one, two... so really, I endorse everyone to please go get your PSA testing," she said. "It's just blood work and it will save your life."

Riders from all walks of life gathered for a poker run, stopping at five locations across the Valley, and even though their passion of bikes is what brought them here, caring for each other has kept them together.

"We do tons of charity work across the state, numerous states, but it's very important to bring awareness and you'd never know we have regular jobs during the day," Gina Ritchie said. "This is just something we do at night on the weekends, but we give support back to our community, to our families. However we can help, we're there to support."
