A cyclorama of a sea voyage sounds fantastic! I wish I could see that one too. It's not on permanent display, is it? I will be in Boston next week...

I didn't know that about the saplings! I wish I'd planned ahead enough to take the bus tour. But then there wouldn't have been time for the caves, and I loved the caves... oh well, as my dad commented, even on a two-month road trip there isn't time to do everything.
