> The city boundaries

Brandolini alert. It only took me 7 seconds to Google search to disprove this statement. How long until we have an auto-bot that will just reject stupid, lazy, false comments like this?

My Google searches:

    > los angeles city density
    > 8,210 people per square mile

Next:

    > new york city density
    > 29,303 people per square mile

So, NYC is 3x the density of LA.
