I heart New York, but face it, the city that never sleeps has its hazards and they’re constantly changing. A decade ago, pedestrian casualties involved cabs and run-ins with their drivers. This week, my New York City travel hazards included Carrie Bradshaw look-alikes and their iPhones. True, I wasn’t dodging bullets— just super models with text messaging addictions mowing me down on the sidewalk. (P.S. They don’t get mad when you use the word “addictions” if it involves electronics and you call them “super models”.) Yes, they were light weights so the collision wasn’t harmful, but you can’t let your guard down. Heads up: Mr. Big with a Blackberry could be just around the corner and concussions and travel don’t mix.
