SACRAMENTO, CA - Long before most of us knew what it meant, Tim Castleman was "going green." He walked or rode a bike to get around -- and when he had to drive, he saved gas.
Boy, did he save.
"I got the lead out of my right foot and turned it into gold," said Castleman. "It's money in my pocket."
Castleman says he saves 50 percent over other drivers. That's what Castleman says he kept by keeping his speedometer at or under 55.
"Once you get used to it, it's a lot more relaxing, a lot less stressful," he said.
