Civil War sites have always been my focus, for the last 25 years. I do hunt Seminole War sites, too, but CW is the main thing for me. Whatcha' wanna know?
Important to remember that 'boundaries' of battles are often misplaced or simply guessed at. Especially in smaller or less famous battles. Often, skirmishes were fought around the battlefields and among retreat routes.
I started this hobby as a coinshooter and now it's primarily relic hunting. Of course I call it amateur archaeology.
Something neat about coming across a small skirmish site. You find a few Confederate rounds here and a few Union rounds there, all in a narrow line. It's neat that you can play a bit of C.S.I. all off of what YOU come across!
