Not that this matters much, but here is a link that details the Carlisle Indian School. It went through use as a Calvary post, Indian School, and morphed into the US Army War College which is what my pop was stationed there for....
What is wild about the pics in the link are... I have no idea if the gym in the photo was on the same grounds, but I used to run on the second floor outside ring as a kid. I remember this aspect indelibly. And the white buildings on the outside. The ones we lived in were made of stone, but looked exactly like this, two story structures, and one walked out onto the athletic fields where history was created. I think about those fields often. Had nary a clue back then what they were.
Burned into my memory. That, and the Motown music, and dime ice cream bars.
