St. Simons Outfitters was owned and operated by Larry Kennedy. Larry manufactured the Xuron vise which was the old vise sold at the Angler's Roost in Manhattan decades ago. Jimmy Deren took over manufacture when the Darbees died. After Deren died Larry took over the manufacture under the Xuron name.
I believe there is Kennedy's with limited fly supplies for coastal fishing located by the airport(Sage dealer). If I remember correctly, It is Larry's son. The One Fly located downtown Brunswick is an Orvis dealer I believe. One fly is a great little shop for all around camping backpacking.
