North Dakota oil boomtown: 'American dream is here'

The oil boom has been a blessing and a curse to the North Dakota city of Williston - crime is surging, women are afraid to walk the streets alone and homeless jobseekers sleep rough in sub-zero temperatures.

But for Carl Trudel, a 37-year-old maintenance man at the Fox Run motorhome park on the city outskirts, it's also a chance to chase the American dream.

He told the BBC why he left the Florida sunshine behind to move to the frozen north in 2012 in search of a better life.
