Description
This is a map of a central portion of the United States showing the boundaries of the PPN4 Great Plains PD Team. That includes all of Indiana Kansas Kentucky Missouri Nebraska Oklahoma South Dakota Tennessee and West Virginia as well as parts of Illinois (its southern half & some countries in the northwest part bordering Iowa). There are both red lines and blue lines on the map but their significance is unclear and the boundaries between states is not always obvious.
