The small library on the shanty boat Dotty is stocked with books abut life on the river and river people. Wes Modes, an artist from Santa Cruz, Calif., plans to take a shanty boat down the entire Tennessee River to document the &#39;secret history&#39; of river people, river communities, and the river itself. Modes has already done this on upper Mississippi. The boat named Dotty, after Modes grandmother, will be docked at Volunteer Landing till July 5 and Modes welcomes visitors. The shanty boat is literally a home made shack on a raft. Wes Modes will be accompanied by a first mate Lauren Benz, and by his dog, Hazel.
