You got nine days

Rico says his friend Bill Calloway has sent out an email, encouraging everyone to fly an American flag (of any size) outside their home on 11 September.
It is the tenth anniversary, so Rico is all in favor of it.
Go out and buy one, if you don't have one (you unpatriotic fuck), and get ready to raise it (with some somber ceremony, one would think) on Sunday, 11 September.
