Humorist Roy Blount, Jr. takes an offbeat journey down the Mississippi River, the literal and figurative Main Stream of America. Blount's unpredictable odyssey celebrates the full range of American diversity and eccentricity -- from a wedding ceremony at the Mall of America in Bloomington, Minnesota, to a rodeo at America s toughest prison in Angola, Louisiana.Like Mark Twain, Blount is a displaced Southerner with the wit and wisdom to capture contemporary life. Blount introduces an unforgettable cast of characters and explores what holds this wildly diverse country together. He throws himself into unique Mississippi River events and viewers meet such memorable characters as Garrison Keillor, who challenges Blount to a stone-skipping contest; Winona LaDuke, an Ojibwe activist who twice ran for Vice President of the U.S.; Kenny Salway, a reclusive environmentalist who spent 28 years living alone in the swamp; and Wilbert Rideau, an award-winning newspaper editor serving a life sentence for murder.Many of the communities and individuals featured in the film are struggling with beliefs and lifestyles that fall outside of mainstream culture. There are Native Americans battling to reclaim tribal lands and traditions; African Americans working with Greenpeace to fight environmental racism; and homesteaders contending for the right to live in old boathouses. Ultimately, the film celebrates diversity, eccentricity, and freedom of expression, as Blount concludes that America is not nearly as homogeneous as he feared. With its unusual blend of humor, irreverence, and insight, The Main Stream will stimulate animated discussion in a range of courses in American studies, history, sociology, ethnic studies and cultural anthropology.
