My commute to school is about 30 miles, or 50 minutes. If I rode the bike to the nearest bus stop (10 miles, 50 minutes) and rode the buses to school (75 minutes, including 20 of walking and waiting), my commute would take two and a half times as long. It would also be free instead of costing $5.50 in gas each way, and I would burn an extra thousand Calories per day.
