In 2002, this was the only reassurance marker you'd see on Missouri 128 in Grundy County. The route is a short spur from Missouri 146 into Crowder State Park west of Trenton.
Also note the older style: this was a square marker with no white border. There was also no directional banner indicated on the marker. This photograph was taken in July 2002 -- compared it to a later photo from September 2012.
