While traveling south on the 5 Freeway this past weekend, I spotted a white, blue and grey boxy vehicle passing us on the left. It looked like an unmarked ambulance, which I figured was probably a prop car for a film or tv shoot. I didn’t think too much more about it until several seconds later when there was suddenly another one, and then another one, and so on. Five generic ambulances in all. Since I wasn’t driving, I snapped a few photos until they exited onto the 60 toward Pomona as we continued toward the O.C.
