The man playing the part of the pastor at Plimouth Plantation. He was quite impressive! Talked to us for quite awhile about which translation of the Bible he was using (they used the Geneva one, not the KJV) He was really interesting to talk to. At the moment I can't find the name of the real guy he was portraying, but I'll keep hunting and once I do I'll post it.
Update: I think I found him. If I'm reading all the stuff I've found correctly, the real guy's name was William Brewster.
