Tricky corners

We had another snow storm yesterday. Even though the snow is pretty at first, it turns ugly at the edges....This flat surface that *looks* like a part of the street safe to step on, is actually a puddle of more-than-ankle-deep ice water. After every snow storm this puddles appear everywhere throughout the city, tricking pedestrians and driving the NY fashion of wearing rubber 'Hunter' boots. In any color imaginable.
