National Museum of Slightly Bent Stop Signs
A collection of more than 340 stop signs, each bent slightly by a documented and fully explained incident, displayed with their original work orders in a former farm-implement showroom. The museum accepts only signs whose damage is complete, verifiable, and uninteresting.

Office of Acceptable Pause Length
Four beige timing lights mounted above a public counter are the first indication that Ralston Divide's Office of Acceptable Pause Length is not a normal municipal annex. The office appears to be maintained by the Ralston Divide Civic Decorum Board, and its posted function is the measurement and demonstration of "reasonable conversational waiting intervals" for front-desk service, public comment, and routine greetings. The reported hook is a laminated chart showing seven approved pause categories, from "immediate acknowledgment" to "reflective but still civic," with different targets for weekdays and festival periods. Several correspondents mention that residents still refer to the building as the old annex court clerk's office, which suggests a repurposing story, a committee dispute, or both. Public hours remain inconsistently reported.
