I really appreciate this thread. This should be in the "you know you are obsessed with the civil war" thread. Because if you are anything like me you have either
a) researched where markers are when planning civil war trips as part of your stops, or
b) pull over to read and/or photograph markers when driving anywhere or
c) get super excited when you see a marker while driving that you didn't know about and
d) scare anyone else in the car when braking hard or pull a U-turn to get out and read the marker or
e) all the above
More than once have I been with family and made detours for markers, much to the disdain of my family. That's why I always drive!
