The Alma Area Museum is run the by the Alma Historical Society. It's in the old teacher's college, which I think would be a neat building to see, even without the stuff inside! It's hard to tell from their website what kinds of displays they have exactly, but I do see something about loggers, which could be neat. It looks to be less hands-on and more of your typical historical displays. Probably a neat little pit stop, but I wouldn't make a special trip just to visit.
