Found a journal of the trip he took across the country in 1917. He must have been on his way to enlist. They didn’t have maps then, just a series of vague directions. Turn left at the green barn, go over a wooden bridge for a good while. Road might be muddy in the rainy season. That sort of thing.
He drove a 1902 Pan American made in Mamaroneck, NY. He had won it in a poker game in Baton Rouge, betting his father’s Civil War timepiece to do it.
He came back from France a changed man. They all did.
