The queue runs along Sixth Avenue, so there's a lot of foot traffic going by. Literally every four minutes at least, someone would stop to ask why we were lining up. Also, be prepared for a lot of "Wow, I would never do that!!!!!!!!" I guess I'll take that as a compliment...?
One guy stopped and actually gave us $100 to buy pizza for everyone on line. So at least one good thing came from it!
