Commuting by bike "a total benefit"

As you fill up the second time this week, consider Jenna Cochran, who's figured out how to avoid gas stations, lose weight and save a couple hundred dollars a month.

In early May, she became a bicycle commuter. . . .

In about three months, she's lost 39 pounds. She's gone from two diabetes medications to none. And rather than spend $250 filling up her Dodge Dakota every month, her monthly gasoline costs have dropped to less than $50. The money she's saved is going toward a new wardrobe.

"This is a total benefit for me," she said.
