We just got a call at 8:15 tonight from a guard at the Coast Guard facility who saw a solo dog that matches Olivia's description.
She was on 1st St SW between V St and T Sts SW and was by the fence at the Pepco Power Plant (see attached map at left for the location of tonight's sighting).
We're heading there now, but even if we don't locate her tonight, this will still be one of our first confirmed, "real-time" sightings of Olivia in a while, so it's wonderful news!
