A few minutes before 6:00 PM two Wednesdays ago, I scurried out of my office in New York City as I usually do, trying to catch the express train back to my home in New Jersey. I walked as fast as my dress shoes allowed me to. Designed for a very different type of use, they caused my shins to strain and my feet to ache as I plowed through the flood of people on the street and headed for the entrance to the underground PATH train. I made it to the entrance in about 10 minutes, as usual, and proceeded to quickly tread the L-shaped staircase down into the stop. Everything about my post-work walk to the PATH up to that point was as it usually was…relatively uneventful. However, what transpired in the next 5 seconds would change every walk I took in NYC from then on and gave me a perspective I will take with me to my grave.
