Maine Experience editor Mike McDade talks in general terms about the challenge of editing several hours of video into a short, coherent story before discussing the particular challenges he faced in combing through a gold mine of footage from the creation of Wyman Dam in Bingham in the late 1920's. The film footage from the dam's construction was used to assemble a story about the history of Central Maine Power (commonly known as CMP) and its forceful, energetic founder, Walter Wyman, who created one of Maine's biggest companies by first buying a small generator on Messalonskee Stream in 1899 that served about a hundred customers.
