Montanans' willingness to walk may reflect the short distances most have
to travel to their jobs, even in a state of 147,000 square miles. About
9 percent live five minutes or less from work, more than twice the

A third of Montanans travel fewer than 10 minutes to their jobs and 71
percent get to work in less than 20 minutes. Only three states had a
higher percentage of commuters with such short trips.
