There are men on motocycles with Polish flags flying from both their handlebars. People are driving through the streets waving red and white banners with POLAND on them. I have no idea what's going on.
I came to Greenpoint with the intent to eat Polish food at a Polish restaurant for the sake of general hunger, but each one of them is packed and even the less popular joints have a 45 minute wait for a table. Across the street from the original restaurant I'd intended to visit, a woman was observing the bikers and their flags from her window.
