Here are a couple of shots indicating faulty Missouri mathematics. These are taken between Novinger and Kirksville.

Left photo taken 9 November 2006 at the east city limit of Novinger. It indicates 8 miles to Kirksville. The right photo (July 2006) is at MO 157 approaching MO 6. It indicates a total of 6 miles between Novinger and Kirksville, a 2-mile discrepancy. Explanation: the Novinger photo gives the distance to US 63; the MO 157 sign gives the distance to the Kirksville city limits.
