Antietam battlefield. Confederate sharpshooters position, near the cornfield.

I foolishly crossed a barb wire fence to get this shot. As I was just about to snap the shutter, I looked to the left and saw an enormous bull about 50 yards away, glaring at me and swinging his tail.

"Sorry, bud - I'm outta here!" I got the shot and got away in one piece, whew!
