I love trains, hate transit buses. On trains you dont have to try so hard to balance yourself. Once you take off your good and then just worrying about the braking at the stop but that takes a while. I used to zone out into a book on the MTA even when standing up. Just post against a door or pole and i was good. But buses? Im weak and i be stumbling and flopping all over the place. Start, stop, start, stop, turn, stop. It takes every muscle in my body to stay upright and not fall on someone's lap.
