Dig Dug is a 1-2 player arcade game in which you have to use your shovel to dig your way through the earth. Stopping you from doing this are two monsters, called Pooka and Fygar, who will continually chase you around. The only weapon that you carry is an air pump, which you can use to inflate the monsters to the point where they explode.
- Dakota Access Pipeline (Wikipedia)
The Dakota Access Pipeline (DAPL) or Bakken pipeline is a 1,172-mile-long (1,886 km) underground pipeline in the United States that has the ability to transport up to 750,000 barrels of light sweet crude oil per day. It begins in the shale oil fields of the Bakken Formation in northwest North Dakota and continues through South Dakota and Iowa to an oil terminal near Patoka, Illinois. Together with the Energy Transfer Crude Oil Pipeline from Patoka to Nederland, Texas, it forms the Bakken system. The pipeline transports 40 percent of the oil produced in the Bakken region.
