From the Herbert Hoover Presidential Library and Museum (which is, itself, in West Branch, a considerable way down the pike from here) I find that Laura Engels Wilder lived in Burr Oak, and that her family helped to operate the Masters Hotel, seen here. I'm not sure if one of those two young ladies is Laura herself. The web site also says that "Laura did not include her year's stay in Burr Oak in the Little House books," so perhaps not.
An easy 5K on the dreadmill this morning. I'll work harder tomorrow. I promise.
