Harmonies of blue grass, country and old-time music fill the air of the Tuckerton Seaport’s Hunting Shanty the first Sunday of every month when the “Pickin’ on the Porch” program takes the stage. Local musicians Linda and Bill Salmons created the program, part of the Seaport’s Folklife Center, 15 years ago. Most recently, after Bill suffered a stroke, Linda has been the sole force behind it. “Musicians come from all over,” she said.
