Favorite thing: I have mock-fired a cannon at just about every Civil War battlefield between Virginia and Mississippi, and few of the better known trenches or depressions among military parks have not at some time or other felt the impress of my devoted play-acting person in their shallows. Visitation at Civil War battlefields is generally small and sadly in decline, with most visitors choosing either to walk or jog these historical paths. If you'll watch for rattlesnakes as you traipse out to the cannon(getting bitten will likely lower your impression of the park), you can get firsthand the views of the opposing battery lines.
Favorite thing: Unlike even the comparatively absent monuments at Chickamauga, Pea Ridge is decidedly poor in respect to monuments and memorials raised to the regiments which fought here. Most of those presently standing are among the most modest you'll see anywhere, having their highest concentration around the rebuilt Elkhorn Tavern.
