Thee's gotta' be someone in the (Leftist) media that will ask the petulant adminstration why they are"closing" open memorials. Is the Lincoln Memorial closed, too? Can you still sit on the steps, or are people being shooed away from even that?
Some protests should be mounted with lots of people just milling about the "closed" memorials. Notify some sympathetic "news" person so it can hopefully be covered by the media in at least some small part.
