Was in the area of Beijing today, around the evening time and off of Lincoln across from the Dollar General was a marked unit. I didn't see any other marked or unmarked cars in the area, but then again I wasn't really looking. I do know he had a pretty good eye on the front of the door though. I still haven't been to this place yet, but did plan on visiting this week, may hold off for a little bit now. Thought it was worth sharing, stay safe out there.
