If you go here:
They have started putting together travel brochures. They have some overall region maps and have started making a couple of "Missouri Civil War Driving Trails".
I think the "Gray Ghost Trail" map is complete and they are working on a "US Grant Trail" map. This an on-going project and they plan to have several driving tours of Missouri. So check back often.
Be sure and click on the "Travel and Tours" link and then the "Your Guide to the Missouri Civil War" link (and then click on the same link in the page that comes up). It will give some general information about Civil War sites in Missouri.
