If you doubt that Phoenix has come a long way, baby, check out this winner. Montebello and 19th Avenue used to be a dusty spot overlooking a sketchy mall with boarded-up businesses and a parking lot with more potholes than asphalt. Now, it's prime people-watching for the thousands who park and ride on Metro light rail every day. Naysayers who thought the light rail was little more than an urban pipe dream need look no further. Hipsters, bike riders, and suburban families line up en masse to board the trains. This park-and-ride spot is so successful that it's caused management of the new SuperTarget to post reminders that their parking lot is for shoppers, not mass transit riders. A public-transit success in this city? From this well-kept and furiously busy corner, you can watch it happen.
