2. Figure out what to do all day
Just because the sky is falling and the entire city is grinding to a halt doesn't mean you should let your whole Saturday go to waste. Potential activities should include the aforementioned eating and drinking, as well as napping, watching the Weather Channel reporters get pummeled by wind and snow on live TV, and truly redefining what it means to "Netflix and chill." Get it? If you really want to go hard, you can do all of the above and clean your apartment, get started on your taxes, and work on that new job search you've been putting off for weeks.
Mind you, these are all just suggestions, so you can by all means just play with yourself all day. There, we said it, OK?
3. Plot out places that are usually crowded
If you just can't cope with being holed up inside your apartment all day, Saturday should be a great day to enjoy places that would otherwise be too crowded for comfort. This should be easy -- think museums, or the restaurants and bars in your neighborhood that are always so infuriatingly packed to the point of you even dreaming of setting foot in them under normal circumstances, because ugh. With that said, you should probably check their websites and call ahead to make sure they're open before you climb into your Gore-Tex.
