Got suspended from the bus for 10 days when I was in 8th grade, and my parents weren't the sort of chowderheads who'd reward their kid with a car ride for misbehaving. It was 7 miles each way (I was a rural kid) and I quickly discovered I could cover the distance in about a 1/2 hr while the bus took more more than an hour each way. When the suspension was lifted, I kept riding.
Distances kept expanding as I grew older -- I had more than 20 miles each way for a decade. But you'd be amazed how little time you save by driving even for that. That base I built while cycling got me into distance and led me to become a multisport outdoorsman. So everything that I have now that I love is because my parents thought I needed to learn a lesson.
