No, despite the desires of a few grumpy residents, we don’t keep state employees locked up during working hours in Idaho. It looks that way, though, if you walk by the vault doors in the hallway of the statehouse.
Those old doors once did keep Idaho’s treasury safe. Banks work just fine as a place to keep money today, so they aren’t needed anymore.
The vault doors were kept in place when the capitol was renovated and expanded in 2010, just because they look so cool. They never close them. It must be a special feeling to enter through those openings and past the shiny and complicated mechanism of the vault door on your way to work, perhaps with a minor niggle of trepidation about their swinging shut during the workday.
