After Melvin Isett, a local entrepreneur, sold his cable-television company, he devoted himself to expanding a local-history collection that now fills multiple buildings with just about everything you can imagine. Farm equipment, mining tools, phonographs and early televisions, furniture, a vintage dentist’s office, a comprehensive collection of cameras, and much, much more. Plan to spend several hours. The guided tour costs the same as the self-guided version, but trust us — the tour guides are terrific.
