Couple to bike across US for student

Aaron and Aleena Roeschley want to pedal for a cause that's close to their hearts.

A year and a half ago, one of Aaron's students at Rio Rico High School, Delia Gonzalez, 17, was diagnosed with aplastic anemia, a rare blood disorder.

To raise awareness about Delia's disease and other bone marrow disorders, the couple will begin a tandem bike ride across the country on Sunday.
