While I'm here, note that Florida has five "Pilot Program" areas where the rules are different from the rest of the state, and from each other. This insanity will persist until 2014....long story, you can read more at Florida Anchoring Issues
Regarding Georgia, the only two problem areas are Little Mud River and Jekyll Creek. Go through at half tide rising and you'll have no problems with either, even with six feet of draft.
Most of the problems noted about the ICW are hysteria resulting from boaters not quite sure of the program. It's really an easy run, with lots of anchorages. Use the Kettlewell stripchart book, it's one of the best.
