Bureau of Seasonal Flags
A one-room municipal office housed in a 1939 WPA annex behind the Ostrander city hall, whose sole statutory duty is the changing of the city's ceremonial seasonal flag every Tuesday at 9:40 a.m. The changing takes approximately four minutes and is open to the public.
Guardrails of Two States
Two parallel runs of highway guardrail displayed side by side under separate placards labeled "Missouri Standard" and "Iowa Standard" occupy a turnout north of Blenner just shy of the Iowa line as the State Line Guardrail Comparison Center. The site appears to be maintained by the Holt-Nodaway Regional Transportation Outreach Council, which still posts seasonal mowing notices on a bulletin board near the gravel lot. The comparison center was reportedly assembled as a late-1980s driver education and procurement exhibit after a jurisdictional disagreement over replacement rail following a series of low-speed ditch entries. The unresolved point, according to the faded panel map, is whether the shorter sample section once included a third terminal end treatment now kept in storage.
Shrine of the Perpetual Folding Chair
Thirty-six beige metal folding chairs are bolted in concentric rows beneath a small open-sided chapel roof, facing a lectern and a backlit sign reading WELCOME ALL DENOMINATIONS BY ARRANGEMENT. The site appears to be maintained by the Vesper Glen Ministerial Association, which posts a handwritten summer schedule for sunrise services, memorials, and what is described only as "quiet seating." The reported hook is not the chapel itself but the chairs: each bears a brass plaque naming the congregation, fellowship hall, or civic lodge from which it was apparently retired. Several correspondents mention a locked side cabinet labeled CHAIR RECORDS, and one notes that the easternmost row is said to have been realigned after a disagreement over proper aisle width. Full documentation will likely require catching the keyholder on a weekday morning.
The Bulk Button Showroom
Thirty-two oversized sample buttons line the gravel forecourt of a low cinderblock warehouse outside Caldwell Siding, each painted to represent a different retail shirt-button style once distributed by Mid-America Fastener & Notions Supply. The company appears to maintain the display in a semi-official way; a plywood sign by the drive still advertises "Trade Visitors Welcome Thursdays," although the showroom windows are papered over and the lot is usually empty. The hook is a rotating pedestal near the road holding what looks to be a 9-foot "pearl finish" four-hole button, reportedly turned by hand for seasonal cleaning and for one day each year during Button Days. Several residents independently referred to an unresolved matter involving whether the exterior samples count as signage, inventory, or "demonstration assets," which suggests the file will bear expansion.
