 If you've got a yard, you may plan on digging in it, like to build an addition, put in a pool, or bury your pirate booty. But you should know that throughout the country, there may be pipelines buried underground. And if you hit one, you've got trouble. Sorry. So before you dig, call 811 to have any buried pipelines located and marked at no charge. For more tips on pipeline safety, visit Pipesafety.org.
