Wednesday's Lake Effect: National Lighthouse Day, Lenses, North Point Lighthouse, Mystery Novel

Wednesday on Lake Effect:

As we mark National Lighthouse Day, we hear about the technology that saved lives and built empires – the Fresnal lens. Then, the Friends of the North Point Lighthouse hope that you experience it as a piece of living history. Later, essayist Mark Siegrist waxes poetical on Milwaukee’s lakefront, and the shores beneath a historic lighthouse become a crime scene in a new murder mystery from Kathleen Ernst.
