Hi bitsalt, As a fellow South Carolinian (Lexington) let me give you a welcome. I know it's enough to drive you crazy thinking of all the adventures just waiting out there for you.
The happiest times of my life were messing around in and on boats. Just being on a boat
sitting at the dock
is way better than most other things you could waste your time doing.
Get you down to the docks and talk to enough people and you might be invited aboard.
Let it be known that you want to learn and crew for a day sail.
Never know what may happen till you give it a try.
Best of luck to you.
