There are some cool locality pattern morphs too, like the "mosaics" that originated from "Edisto Island" off the coast of S. Carolina, and a guy by the name of Ricky Waters collected a different earlier mosaic line in the 90's in Berkeley County, S.C. , and the Edisto Island mosaics where from wild collected stock in 1997 in Charleston County, S. Carolina.
There is also a bizarre "bullseye" morph with distinct circle patterning that are only known from Mitchell County, Georgia as well. And of course the southern Georgia wide-banded types found near the Florida panhandle and on into southern GA. Many of these are known to be contain strong influence of varing degrees with the neighboring "blotched kings" (goini) found to the south.
Oh!, and of course the awesome and very distinct Outer Banks kings off the coast of N. Carolina from Buxton south through Cape Hatteras and Ocracoke Island and further down into the Grand Banks to Cape Lookout!
Anyway, yes, there are definitely quite a few very cool Eastern types to choose from if you look around.......good luck!
