This is a great place to visit if you find yourself in western Wisconsin (not too far from Minneapolis). I particularly liked this picture of my boys working the water pump. (Click on the photo and go to the Caddie Woodlawn set to see more).
Don't miss the wonderful books:
Caddie Woodlawn by Carol Ryrie Brink and Magical Melons a.k.a. Caddie Woodlawn's Family
