If you want to make the trip to SSI there is a great little shop down there. Very helpful! I went for some saltwater flies and spent a while talking with the owner. Not sure what your looking for but i know it is the closest fly shop besides ATL and Augusta. http://www.stsimonsoutfitters.com/ they have a lot more flies then they have on their site.
yeah there is an orvis outfitters in St Simons Island only about an Savannah its pretty good and there is a few fly tackle stuff at Tackle Shack in Brunswick but if you go to Orvis you better have some money to burn
thats what i here about the one in ssi. better have a lot of the dead presdients with ya. mr tom the older man thats works in bsp said that thier is one over in thunderbolt ,ga. but i havent made it over that way yet. thanks for all the help guys. looks like i am at the mercy of the brown truck again.
