pjlla, they have a special celebration at Mansfield once a year. I think it's in the fall, but I could check for you if you'd like. Anyway, they take Pa's fiddle out of it's case and play it at the festival. I'd love to be there for that. We went in the summer, so we only got to look at it.
You could easily do Branson in the same trip. They are very close. When we were there the Osmonds still had a show, but we didn't go. I don't know which Osmonds sing there, but I bet there are sites where you can find show listings for the area. They have TONS of shows.
Sonya, they now have aquired Rock House that Rose had built for Laura and Almanzo in Mansfield. They only lived there a few years before they moved back into the old farmhouse that they built, but it was cool to tour it, too.
Glad you guys are enjoying hearing about my trip. It was very educational, and we found loads of fun things to do along the way. Let me know if you ever want to make plans. I have phone numbers, etc for all the museums. Oh and two places have plays that they put on in the summer. We went to both and they were fun.
