On May 31, 1928, President Calvin Coolidge accepted former Senator Irvine Lenroot's invitation to spend the summer in the Superior area. Henry Clay Pierce offered Cedar Island Lodge, part of a 4,000 acre Brule River estate, as living quarters for the President and his family. Superior Central High School was designated the official White House Offices for the presidential party and served in that role from June 15, 1928, until September 10, 1928. On July 16, 1928, Coolidge welcomed presidential nominee Herbert Hoover to the area for his first public appearance after his nomination. From the steps of Central High, Coolidge announced his support for Hoover's candidacy to crowds of newsmen, visitors, and area residents. Hoover had taken a firm stand in favor of the Great Lakes Waterway and was hailed as the obvious choice for the presidency. During his stay, Coolidge also found time to fish on the Brule River, one of America's most famous trout streams.
