The Miracle of America Museum (58176 Hwy. 93, 406/883-6804, 8 a.m.–8 p.m. daily summer; 8 a.m.–5 p.m. Mon.–Sat., 1:30–5 p.m. Sun. winter; $4 adult, $1 child) is marked by a large log towboat in the parking lot. Inside this sprawling and big-hearted “Smithsonian of the West,” the intrepid museumgoer will find a unique homage to cleanliness: a collection of antique vacuum cleaners. Music lovers will thrill to the sound of the violano, a coin-operated violin-piano combination; the State Fiddlers’ Hall of Fame is also housed here. There’s simply a lot of everything here, from old motorcycles to vintage tractor seats.
