Miles...I did not see a ranger at Oak Hill or at the observation tower overlooking Barlow's position to the east and the Reynolds line across a large field to the west. I stopped and took photos at the Rodes position on the campus of the seminary....from the wording, it was a post battle position and one where the unit moved out. To answer you question, no, I did not and all I learned came from the narrator at the cyclorama...I posted earlier but can't seem to find my reply. It may turn up.
