Tennessee born but Iowa tough.
Actually, both States have been tough for a long time. Do a little Civil War reading: Volunteers from Tennessee and Iowa were in the thick of it at the bloody Battle of Shiloh, with massive losses on both sides. When I was a young man, all of the Iowa regimental flags from the Civil war were on display at the Iowa Capitol. A very humbling, depressing thing to see....they were riddled with bullet holes. The bravery and courage that young men between 18 and 20 years old displayed during that horrible war (and all subsequent wars) is almost impossible to believe today.
My wife's great-grandfather fought at the Battle of Gettyburg for a Pennsylvania regiment. His written accounts of that battle are incredible.
