 All right, crew, let's get her dug. Honey, you want to give me a hand? I'm planting that tree, remember? No matter how large or small your digging project may be, no matter how urban or rural, you must always call 8-1-1 before any digging project. 8-1-1 is our national one-call number, alerting your local utility companies to come out and mark any lines they have near your dig site.
