Following the Herndon's shutdown of the day laborer center, a reader noticed this:

If you drive into Herndon on West Ox Road from Loudoun County, you'll see a flashing electronic message sign reading "Day Labor Center CLOSED." Guess they're driving to discourage folks from Ashburn from trolling for folks to hang drywall in their particleboard houses.

Now if they can just point a flashing electronic arrow in the general direction of Panama, we'll be all set!
