Hit Snowden Virginia on this date and bought some groceries at a small store. If I recall, I got a hunk of cheese too. I used two methods for food. For the most part I bought food along the trail. Occasionally the choices were limited, like Snowden, but in other towns we had full size super markets. I also had some food mailed to me, but that was limited to items I knew I couldn't get along the trail.
For dinners, I had Mac and Cheese, way too often.
I didn't take any photos on this day, but if this google street view works for you, this is a shot trail north leaving the James River Valley.
Here is a streetview of a AT Parking area east of the river. Doubt that it was there in 1974.
