Sounds like you made the most of your trip given the fact Sandy came along about the same time. I'm heading down next week for a few days. My wife is already there and reports constant wind from NE at 20-30 mph. Hope that subsides some in the next few days, but if not, I'll cope with the conditions as you did.
I've looked around a little at that creek and mangrove "ponds" you fished between winding Bay and Half Sound but haven't fished there. Did you wade the creek? How did you access to fish it? I want to give that a try.
My new (untested) theory for the Savannah Sound tailers is to bury a small snail imitation fly in the sand, back up a ways and stand there waiting for a bone to come along and dig it up as that's what I think they are doing. Only problem is I may have to wait for years, so I think I'll look for more cooperative fish!
