At least until the 2010 Census, this is the highest population figure that you'll see on a Missouri city-limits sign.
This photograph was taken in September 2005 on the service road for Interstate 29 and US 71 just south of NW 72nd Street in Platte County. On the other wide of NW 72nd is the city-limits sign for Platte Woods, a small town surrounded on three sides by Kansas City.
