Sounds like a a real eye opening expiriance Sundance. I've yet to get to the closest fort to me it would be Fort Tajon ... in the Tehachapis.
Have come across Old American Indian Villages, Abobe Houses ect... but no Battlefiellsd Sites like Shilo... That must a been a bewilderin' experiance.
Good description of what you felt there Sundance...tryin' to put myself there in my present state of bein'/age. I'd stay but think I'd be with the Cannon Cockers sayin' FIRE!
