Fort Robinson is our base this week, we spent the day exploring all of the museums, and the grounds within walking distance.  What a unique place.  It has been here since the 1700's as an Outpost, Crazy Horse was actually killed here.  The history is so diversified, I was fascinated by it all.  There is an exhibit of mammoths that had locked horns in battle and could not get apart, which are preserved here.  There is a reminder of the German POW camp,  A must see.
