Depends on my mood. It's 15 kilometer but when the weather is good I take my bike, when it's snowing I take the train and walk from the train station to my school for 15 minutes and when the weather is just average (rain, wind etc.) I take my scooter.
Mine is about 25 miles away from my house. I travel by car.
I wish I lived on campus sometimes so I could walk and save money since gas can't stop going up. And I think it would help me from skipping too much class lol
