Ive been in Taw Caw Cr a few times shooting fish. For a long liner or spider rigger it looks IDEAL for crappie. There's some big cats in there too...or atleast there was some 20 years ago. I forget the name of the creek (maybe Black's bottoms?!?) It is right out of Taw Caw Creek to the left. It too looks great for crappie. I recommend you pick you up a good map of Lake Marion and study it some. And beware of rough waters if the wind picks up while out on those Santee lakes.
Health nuts are going to feel stupid someday, lying in hospitals dying of nothing.
