In today's Washington Post we learn how the Pentagon is celebrating Freedom through the extensive use of snow fencing:

The march, sponsored by the Department of Defense, will wend its way from the Pentagon to the Mall along a route that has not been specified but will be lined with four-foot-high snow fencing to keep it closed and "sterile," said Allison Barber, deputy assistant secretary of defense.

The U.S. Park Police will have its entire Washington force of several hundred on duty and along the route, on foot, horseback and motorcycles and monitoring from above by helicopter. Officers are prepared to arrest anyone who joins the march or concert without a credential and refuses to leave, said Park Police Chief Dwight E. Pettiford.

In other news, the campaign slogan for the Walk (or is it a March now?) has changed from "America Supports You" to "Keeping America Closed and Sterile."
