Wendy - I found that one really interesting on both the lines she looked at - classic goldrush stuff in that the money was made by those who supplied the miners (some well known names in there) and the women's pioneer ancestor in Maine.
I hope that as we aren't getting all the episodes they selected the most interesting rather than those they think are most well-known. I don't think I've ever seen Helen Hunt in anything, didn't prevent appreciation of the programme.
