Volumes I, II and III were a huge success! Here's Volume IV of "All Worth Their Salt: The People of NWI." It is a collection of 100 interviews human interest columnist Jeff Manes has written about those hailing from Northwest Indiana. The folks Manes showcases are mill rats, sod busters, hash slingers, boilermakers, barbers, bricklayers,truckers, teachers, tree huggers, eccentrics and altruists. The people of Northwest Indiana are salt of the earth. Truly, ordinary people who do extraordinary things.
