How to close a moment that is always open

This is the World War II monument, which like most such places in Washington is always open. For that reason, I like to wander about the Mall at five o'clock in the morning, when none but the occasional jogger will interrupt the reverie. But because of the so-called government shutdown, someone (I wonder at whose request?) went to the trouble and expense of shutting down an open monument. How much did that sign cost to print and post?

Happily, a passel of WWII vets came to town yesterday, and with the connivance of some Republican lawmakers, they took the law into their own hands and visited the memorial anyhow. Good for them!
