Jackson County was the site of the first recorded train robbery of a moving train in the United States. On October 6, 1866 the Reno Gang robbed an Ohio and Mississippi Railway train, making off with over $10,000. 
Jackson County has the second longest 3-span covered bridge in the world; The Medora Covered Bridge. After a recent project to completely refurbish the Medora Covered Bridge, the nearby town of Medora now holds an annual event at the bridge. The bridge is open for pedestrian traffic and site-seers. Another long neglected covered bridge, the Bells Ford Bridge, believed to have been the last remaining Post Truss bridge in the world, succumbed to neglect, collapsing into the White River on January 2, 2006.
