A year ago, almost to the day, I moved from suburban New Jersey to Manhattan. Over that year, I've done a mixture of subway and bike travel. The last few months, I've done it almost exclusively by bike. On Friday, I took the subway for the first time in two months! I was just too tired after a few days of very heavy riding.

Car driving is awful. It's much more stressful than we know. When you bang your head against the wall repeatedly, it feels great when you stop. So it is with car commuting.
