Could this be the Fredericksburg, Maryland Dog Mart which was also known as the Dog Curb Mart?

"The mart was scheduled for October each year to coincide with the beginning of hunting season in the area. This provided hunters with the opportunity to purchase hunting dogs. At that time the event began to gain nation-wide attention. It was the subject of a Pathe Newsreel feature in 1928 and Time magazine featured the Dog Mart in an article in October 1937. In 1938, 7,000 people and 641 dogs attended the event." Source: Wikipedia

This may or may not be in autumn but this picture reminds me of how close I used to get to the earth when I was a kid. I can remember the smell of dirt, dry leaves, grass. It was not unusual to be rolling around in the grass. During the very early part of spring I was thinking about how what it was like when the snow started melting and little rivulets would appear of running water. We were so close to all of it back then.
