Saw a Whacko this morning

I have to back in in my work truck...and put out cones. Picking up the cones before I leave forces me to clear the front and rear of my truck so when I pull out there is not a kid sitting on my bumper or standing behind my truck. I've found these idiots 4x in 25 years. 4 lives saved? I like it when the people just stop in the middle of the lane and put their flashers on, like it's permission to stop there?
