From the NYTimes Laughlines:
Barack Obama still maintains he will have an open-door policy with Republicans. Of course, to maintain some semblance of order, access to that door will be done by a system of purple tickets. – Janice Hough, Palo Alto, Calif.
(Purple ticket reference, if you find it obscure)
That's daughter of my good friend, and Ms. Angus coauthor, Jerry Hough.
UPDATE: A little more on Purple Tickets.....
Problems were reported at other entry points as well. There were delays at the Orange Gate, and a power failure at the Blue Gate apparently caused the screeners to have to pat down attendees instead of sending them through metal detectors. But nowhere else were the problems as significant, or the dissatisfaction as strong, as it was among the Purple Ticket Holders. Dianne Feinstein has called for the Secret Service to get to the bottom of the matter. It may be that President Obama should get Chief Justice Roberts prepped for a third rendition of the oath, for the many people whose tickets could not get them access to the festivities.
