Attractions between NJ and Yellowstone

We were traveling on I-90 from Billings to the Little Big Horn National Memorial and stopped at Hardin, Mt for the night. I picked up a brochure on the Big Horn County Historical Museum. We decided to check it out. This is located in Hardin, Montana and is about 35 years old. In this time period they have moved 26 various historical buildings to a 35 acre complex. These buildings and a train station have been filled with many antiques which have been donated by local families. There is also a large barn filled with vintage working fire trucks and other restored tractors, automobiles, farm equipment and various farm implements. The railroad station looks like the station master has just stepped away from the counter for a break. All the station equipment is there and looks they work. The farm house and barn were built on the site in 1906 and has most of the original type furniture. They even brought in a slaughter house and meat market. All the buildings are arranged as a small town and connected by a boardwalk. They were adding a new building when we were there. This was definitely a surprise find. If you are passing this way, I recommend you also check it out.
