Coming into work a few years ago around 5:30 am, a construction crew had just cleaned up from cutting concrete on the interstate. I merged onto the interstate behind a large 18 wheeler, which was producing a spray paint like mist of liquid concrete, that coated my face shield, and the rest of my entire frontal side, rendering me
totally blind at 60 mph...I managed to do an "emergency landing" on the shoulder, and wipe what I could off, and get my heart rate down....
