Delivering a blend of local history, environmental issues, education, entertainment, and fresh air, Davenport's River Action will present a series of outdoor presentations in the second month-plus of the annual Channel Cat Talks and Riverine Walks: weekly programs that, from July 8 through August 2, will address such topics as the music of local jazz legend Bix Beiderbecke, the Hauberg Estate, the Hennepin Canal, and even the Channel Cat series itself.
