Replying to New Year's Eve in New York City

Saw someone's Facebook status today and it got me thinking.

Anyone ever done New Year's Eve in NYC? I assume a lot of you probably have actually.

I'm looking at getting some friends together and going to Nas at Radio City Music Hall, proceeded by festivities at Times Square, which is less than a half of a mile away.

Anyone who's got experience with New Year's Eve in the city, care to share your advice? Parking, bars to go to, etc.?

I have some experience with the city so I wouldn't be going in totally blind. (I live 3 hours away.)

Serious answers +K

Thanks NS.
