Hi Jim, You are welcome. I know what you mean about some of the other forums (we won't mention any names). I live in North Myrtle, I've lived in the general area a little over 25 years. I've never been to Edisto, but hear it is beautiful. I'll have to get down that way and check out the lighthouse.
I did this tour several years ago and loved it. It should be aboard one of the Fury Catamarans.
An awesome experience, a great staff, and the margaritas hit the spot.
