Wow. They posted this awfully late. Usually it's like 48 hours in advance.

Fairfax County Police Officers from the McLean District Station will conduct a sobriety checkpoint to deter and apprehend intoxicated drivers from 11:30 p.m. Friday April 8, to 2:30 a.m. Saturday. All motorists will be stopped and drivers will be checked to assure that their abilities to drive have not been impaired by alcohol or drugs.

I'm going to call and complain to the Public Information Office on Monday. I sent an email to Internal Affairs about unannounced checkpoints like a week ago and still haven't heard back.
