It's always smart to keep your eyes open for red flags whether it is in your dating life or maybe even in your yard at home.

And unlike those red flags you run into out at the bar, the ones in your yard might leave you wondering what to do next.

Why Are Flags Places In Yards Without Homeowner's Knowledge?

You come home from work and you suddenly notice a bunch of flags among the grass sticking up out of your yard. You didn't approve of this.

Unfortunately for you, it might not matter. Those flags are likely from a utility company who has to make repairs to something buried near your house.

There is an entire color-coded system that utility companies have agreed upon using when it comes to marking their pipes or wires in someone's yard. Not only does it keep workers from digging in the wrong place, but the system also helps prevent the crew from accidentally damaging another company's property.
