Here's a totally different meaning of YOLO. (You only live once). I wondered how many accidents happen like this. After all it will only take one pot hole in the ground to knock some off the back. Had one of these guys fell off the truck, our driver would not have had enough time to make timely adjustments. We were doing at least 25 mph. What amazed me even more was when all four men started smiling and waving at me after realising I had taken a photo.
