I was looking at cards the other day at Cabellas & noticed they are in zones. If the state line is the border for the zones as in Georgia/S.C. & there are lakes on the border which zone do you buy ? The guy at the store said you had to buy both. Would the one for S.C. have lakes Hartwell & Clark Hill or the one for Georgia or do they split down the middle of lake ? Doesn't make sense.
