It was a long time coming, but Boise's bike share program, dubbed GreenBike, finally hit the streets in April with 114 specially designed cycles at 15 rental stations located around town. The GreenBike program started yielding public health benefits almost immediately. Within two weeks of the rollout, GreenBike officials estimated Boiseans burned about 7,000 calories in 251 trips. During the same time, riders offset 156 pounds of carbon dioxide, equating to the emissions produced by burning 29 gallons of gas. Talk about a social service.
