October usually is about the end of the main Laura Ingalls Wilder season for the year. If you plan a Laura trip after that, make sure you call ahead. They may or may not be able to accommodate you by opening the museum, etc. or giving lists of what there is to see. On the plus side you get autumn foliage and then snow photos. I called around to find out when the Laura museums were officially closing for the year.
