I was on a 2-man crew installing underground cable. Other guy was running the backhoe as we prepared to bore under a road and kept hitting a "rock". I jumped into the hole with a shovel to see what & how big it was. The "rock" turned out to be a 6" natural gas main, with serious chips knocked out of it .

If I remember corectly, we called the gas company and took a much needed break. So much for engineering blueprints!!!!!
