Not an expert in
SC, but your lloking at freshwater around you in Columbia. I know there are someplaces there, but never fished them.
Your gonna have to make a drive to Myrtle Beach or Charleston,
SC which are both nice weekend getaways and not too far to see some SaltWater.
Here are some answers to your questions:
1) Spot in MB and Charleston, just got to put in a days work.
2) Not that I know of.
3) Yep, Great spots on the coast.
4) Not sure, maybe on a dive on the coast.
5) Not like the Corona commercial, but nice. CROWDED in season in the tourist spots.
6) Pretty sure, heard some good dive stories years ago.
7) No Idea???
8) Some very nice places there in Columbia and just a few hours away (Charlotte, MB, Charleston, etc...). IT's HOT there in the summer though, whew is it HOT!
