That is Elaine in front of "Old Faithful" this was a combo trip celebrating her 8/31 retirement and our 41st wedding anniversary on 9/5.
BTW we thought "Old Faithful" was overhyped but the geyser at the top was on one of the many off the main roads and we found it to be a great time.
For those who have not been there (as we had not) it is hard to describe the size of this national park. It is huge and has a large assortment of things to see and study.
