The MKT Trail is an 8.9 mile spur line from the old Missouri-Kansas-Texas Railroad that runs to downtown Columbia, MO from near McBaine, MO. The city of Columbia maintains the first 4.7 miles of the MKT Trail and Boone County maintains the remaining 4.2 miles.
"Mile marker 5.4" is a photo by Columbia resident Gary Dietrich. Dietrich's book is "Seasons of the MKT Trail: A Pictorial Journey."
