Phil Hamm, 77. - 

The oil boom has brought all sorts of changes to western North Dakota. Billionaire Harold Hamm has had a big hand in it.  His company, Continental Resources, is the biggest oil producer there.

Then there's Phil Hamm, who moved to Williston, North Dakota, before the oil industry arrived. He had a few things to say about the changes he's seen, when Todd Melby interviewed for his series "Black Gold Boom."

Todd Melby's series, "Black Gold Boom," is an initiative of Prairie Public and the Association for Independents in Radio.
