肮脏的财富

National Geographic Channel tromps into the wild with blue-collar pionrs who shirked conventional 9-to-5 carrs to make their living in the dp rivers, soggy mudflats and wild backwoods of America. Filthy Riches, a new series premiering Sunday, April 20, at 10:00 p.m. ET/PT, travels the country with industrious Americans who prove they&#39re not afraid to roll up their slves and get their hands dirty in order to make a living.
