Recently discovered a YouTube channel by Mark Laila called Soft White Underbelly.
He does interviews with lots of homeless people, meth addicts and prostitutes etc but the series of interviews he has with the people of Appalachia is absolutely fascinating! Totally worth watching!
These two were great!
