This was posted in the comments, and I wanted to bring it up to the forefront to make sure everyone saw it:
Here is a schedule of events at the Betsy-Tacy houses for Saturday, July 17. The LIW conference events will end by noon Saturday, so those not going on the field trip to Walnut Grove should certainly consider attending these events at the nearby Betsy and Tacy houses. Remember that the Betsy-Tacy houses are open and holding events Friday morning of Laurapalooza, as well, so attendees now have two different time slots available to see the Betsy-Tacy houses.
