I take the train from northern VA to downtown each morning. It's convinient for me because I aviod traffic, can read, and the train station in both cases is little more than a block or two away.
But busses. I use to ride the bus in high school. It was humiliating. About all the other white kids at my HS had cars by sophmore year, but I was riding the bus until I was a senior. It was cool if you were black, but the black kids wouldn't really integrate a nerdy white boy in with them. And it was humiliating among the whites and there was no way I was ever getting a girl with no wheels.
So my folks were too poor to buy me wheels - big deal. I got food and a roof over my head - that's plenty. I decided to get a job to try and buy a car, but then when I had the money saved and earned my parents wouldn't let me because they said I was too young (they grew up in another state a long time ago and the age was much higher for drivers liscences). In anger I blew the money on junk. Probably a bad move.
So I stood out every morning watching my classmates drive by as I waited for the bus. And then I remember the prom night. No car, but I was volunteering to hammer signs for a candidate for school board who came in dead last among a field of 14. So I loaded up a wheel barrow with the signs and a hammer, pulled it over the major bridge in our town to walk 4 miles to the down-town area and started hammering signs as I watched my classmates drive by with their dates to the prom.
The result of this is it breaks you of any influence or fear of doing what you think is best no matter what others may think of you.
So riding the bus is a good thing.
