As for fracking, it is the process that makes oil extraction possible in the dense rock and shale of the Bakken. Basically, equipment creates thousands of fissures in the rock, and then sand, water and even ceramics are blasted into the formation to prop open the fissures to let the oil flow.

There are chemicals in the "frack water," and there has been some environmental backlash. So far, it looks like the drilling method will be permitted, but if fracking were limited or disallowed, the Bakken boom would go bust.

For now, it is full speed ahead, and that means hiring will continue at a rapid clip. The trickle-down is ubiquitous, and the money is eye-popping.

Shelter for workers

If you have a license and no criminal record, you can get a six-figure trucking job almost overnight. Real-estate construction is almost as frenzied as the oil drilling, and there's a huge business in housing the workers.

The business is sometimes referred to as providing "man camps," although some women stay there, too. It's a lot like most people would think: trailers in rows, with workers sleeping in simple single rooms or bunking with others.

Food is served in a cafeteria, and companies such as Halliburton (HAL, news) and Schlumberger (SLB, news) pay an average of $120 per person per night to safely house and feed their workers.

"We have almost 3,000 bedrooms under management, covering over hundreds of miles in the Bakken," said Brian Lash who runs Target Logistics, the biggest "man camp" provider in the Bakken. (It describes the camps as "lodges.")

Lash has dealt with booms before, and his company's actions indicate that he believes the Bakken has room to grow.

"We've got almost $100 million in buildings and underground infrastructure so far in the Bakken," he said in August. "We have another three projects that we're about to start."

In Williston, the "man camp" is a better place to be than the Wal-Mart parking lot or the back of a pickup. But most people don't care, as long as the work continues and the money continues to flow with the oil.

"I have a bed in the back of the camper shell," Terry Ayers said as the sun began to set on the back end of the Wal-Mart parking lot. "You just can't get back there (right now). It's still too hot. You have to wait until the sun drops."

After a little back-and-forth banter, he sums it up: "All for a job."
