Parties. Lots and lots of parties and drinking. And if you're lucky enough to live in New York City, you stay away from Times Square and ring in the new year at home with a party. But it's always a good idea to do the Times Square thing, just to have done it. There are a ton of people and it's a big party in the middle of the city, and at midnight a ball drops, and it's pretty awesome.
I'm pretty sure that there's going to be a big party going on here.
