What are the NYC laws on an open container in public?

It violates NYC Administrative Code 10-125 to have an open alcoholic beverage ( > %0.5 ABV) in any area where the ‘public may congregate’ (important)

Elaborate:

Licenses for events such as block parties and for restaurants that have street seating are exempt but I’m sure that opens up another set of rules anyway. I guess to break down my question, is it illegal for me to sit on my stoop, away from the sidewalk, and drink a beer? The answer to that is ‘yes’. “The law defines it as an area “to which the public or a substantial group of persons has access, including, but not limited to a sidewalk, street or park.”” [brownstoner]. Apparently ‘private property’ does not denote ‘area where the public may NOT congregate’. This is obviously a grey area and can probably be contested to some extent but the laws seem to be quite broad and give both the officer a chance to interpret them one way and the drinker to interpret them another. Well, at least pretty much everyone in NYC does it.

Reason For Asking:

I sometimes enjoy a beer on my stoop but I generally hide it for fear of getting a summons.
