Marty’s photo of the day #3721: During our American Prairie Reserve visit earlier this month, Deb and I walked many miles, and our dog, Nellie, more than quadrupled whatever ground we covered. Despite all that exploring, one of our most enjoyable days occurred when we found a grassy section along a high, sheer bank of the Missouri River. There we sat for hours, relaxing and watching the river go by. It was wonderful! My only exercise came from when I hit the timer on my camera and hurried into position.
