A Scary Job

I was on the overpass here in Ozark and they are working on expanding it. There is always construction trucks and guys out there during the day pouring concrete, painting lines, you know, the usual construction stuff. Today, I was on the overpass and there were about 7 workers, each using a jack hammer on the overpass, right above highway 65. They were all tethered by a bungee cord, I guess just in case they jack hammer too much and fall through. I don't know what is more scary, their job, knowing that at any moment they might fall through the cracks (literally) or me stopped at a light on the overpass right next to them, while they jack hammer out the floor that I'm sitting on.
