Antique Fishing Lures (A)

Saturday, April 11

Local antique fishing tackle historian and collector Bill Sonnett shares his vast knowledge about how our area became the home of the tackle industry at the beginning of the last century and how the hobby of collecting antique tackle has changed over the last 30 years.

A program every fisherman (or woman) will want to attend! FEE: $3/member; $5/non-member. Pre-registration appreciated.
