As the "neighborhood" is a somewhat confined area, why don't one of you DC Freepers create your own flyer, outing Code Pink, ratting on them about their support of Al Qaeda, and put these flyers in the mailboxes of the surrounding neighborhood (just a few blocks in the immediate vicinity would do). And of course, tell them what you, as good patriots, believe and why you are protesting. You could also tout Free Republic (and give them the website address on the flyer). Fight fire with fire, and get FR's name around out there. A copy machine and computer to do the flyer on and you are in business. Plus minimal legwork, just hitting the nearby homes.
The city should tell us all to take it somewhere else. We are getting reports the guys and gals are very excited and cheer when they know we are there.
