I recently took a trip with my friend Kelly Pezel down to Chariton County, Missouri to visit the place where the Ingalls family bought land near the town of Rothville. I hadn't ever been there before so I was glad to get a chance at visiting one of the last places the Charles Ingalls family visited that I hadn't visited yet. 

This is the brochure the Chariton County Historical Society puts out:
