Rob,
That is some crazy October weather. I just checked and it's currently 71* on Hilton Head. That's the kind of October weather I like on HHI. I'm glad to hear you had a good trip and didn't mind the heat.
I'm entertaining the idea of a November long weekend, but haven't pulled the trigger yet. I'm hoping the 70* weather will still be around for a few more weeks.
Cheers,
Will
