As a deadline hit for protesters at the Occupy D.C. encampment at McPherson Square to stop camping, occupiers draped a massive tarp over the statue of General James McPherson after which the park was named while chanting “Let us sleep so we can dream.”

U.S. Park Police haven’t yet responded, but are expected to start enforcing anti-camping regulations today. Under those rules, Occupy D.C. protesters at McPherson Square (and Freedom Plaza) could maintain a 24-hour vigil but not sleep at either site.

Our own Benjamin Freed is down at McPherson Square (follow him here), and we’ll have more updates as events warrant.

UPDATE, 12:45 p.m.: This isn’t the first time that protesters at Occupy D.C. have tried something like this. In December, they raised a barn, leading to the arrest of 31. Earlier this month, they constructed a roving art display that was taken down by Park Police. In other actions, in November some protesters occupied an empty school building near Franklin Square and clashed with police (and cars) at the Convention Center.
