Not one of us knew, so this one’s for her and everyone else afraid to park freely in D.C. today: Parking meters are not in operation and motorists should expect a holiday traffic pattern this afternoon, according to the District Department of Transportation.

For the six of us still at work, this means there will also be no rush-hour restrictions or reversible lane changes. However, some things never change regardless of the holiday — expect major Metro work all weekend.
