Check out the Pennyroyal Museum in Hopkinsville-
They have a great set up relating to the area and its history! They have a very nice display on the old Hoptown Hoppers! Check out the photos!
Also, this is simply a GREAT MUSEUM! They don't have a ton of space, but they have done a lot with what they have.
They have amazing displays on the Knight Riders, Edgar Cayce, and other odd and interesting people and events in history linked to the area.
