"Explore the Busy Beaver Button Company"

The Busy Beaver Button Company opens its doors as part of Obscura Day for a tour that will show why its more than just a clever name for the locally-based "button-maker to the world." Observe how the company's solar-powered factory makes its buttons with the help of a geothermal heat pump, then pop into the button museum to see more than 9,000 historical buttons. Space is limited to 20 people, so RSVP quickly.
