These photos are wonderful. It is like being there.
I was a freshman at Benedictine College in Atchison in 1962-1963. One route from Kansas City to Atchison is on Missouri highway 45, which is also called 273 in many stretches.
When I came back to visit in 1983, I was struck by the beauty that I had seen that I did not appreciate before. Going north from Weston to the left turn to Atchison, the Missouri River is the left and low hills are to the right.
