There's a little-known law that requires every single t-shirt and hoodie sold within the city limits of Ithaca, NY — a city in which I spent several years as a student — to be emblazoned with the slogan "Ithaca is Gorges" or some variation thereof. In summer, this seems like a cute idea. In winter, you realize you have sworn allegiance to a place that chose a collection of gaping, icy maws as its local symbol. It's currently around 13 degrees Fahrenheit there, expected to dip below zero over the weekend, with a hazardous weather warning for "bitterly cold Arctic air." Braving the half-frozen New York subways is nothing compared to wondering how many inches of ice will blanket Ithaca's steep, deadly hills on any given day.
