That's what my friend mentioned to me.
Once you're at L Italia, you should be able to hear the drums & see the crowds. Or head over to where Hester St & Mott St intersect. It supposedly starts @ 1pm, but I'd be there at 10am because there's plenty of things going on.
Be prepared for the HUGE crowds & loud noises.
Also have some sense, because there will be pick pockets in addition to the undercovers. Leave the most expensive gadgets at home unless you absolutely need them.
That's another reason why I haven't gone to NYC that often.
Anyway.... I have other engagements, so I won't be there this Sunday, but I'll make an appearance there in August.
