Don't you or didn't you live in NYC? My understanding is that there is a fairly long running large gathering of people somewhat in the middle of Manhattan which culminates for some odd reason around 12:00 after which the fine members of the NYPD manage to scatter everyone off into the side streets or down into the subway.
That aside, most cities have at least one or two staged events for the public to attend on NYE which doesn't draw quite as well as it does in NYC however anywhere from a few thousand to double digit thousands is common...at least in the cities I've live in or near.
Again....pick your gathering for whatever reason. A lot of it is the mere fact that you are there is that is the attraction. You're smarter than Rojo....which isn't necessarily a compliment...so I'd expect you'd get this.
