re: Battlefields of WWI fading into greenery

went to party at a guys home in the Oak Hill section of south Nashville. He had an amazing collection of Civil War era artillery and small arms projectiles. He had hundred of mini balls and probably 30 cannon balls. Everything he had was found on his lot. Turns out his house was built on the site of a union artillery battery and the Yanks and Rebs spent a good bit of time firing back at forth at each other.

He said he hit one cannonball with his mower blade and was damn lucky he didn't get killed.
