Josie, 7, is one of a small number of students at her elementary school on the Boise Bench that commute via bike. “When it’s just a regular day, a few people ride their bikes,” she says. “Probably 20 or so.” She plans to keep riding as an adult. “I just love riding my bike. It’s a fun activity and I think I’ll do it for my whole life.” When she grows up, Josie plans to be a teacher, artist, astronaut and dog walker.
