Perhaps a strange choice to finish with, but it is interesting for a couple of reasons. First and foremost, the photograph was taken in Lincoln, Nebraska on the night of July 25, 1936 when the minimum temperature fell to only 91°F in Lincoln. This was the hottest night ever experienced anywhere in United States recorded history outside of the desert Southwest (although a minimum of 92° was reported at Leavenworth, Kansas on August 10, 1934 but is suspicious). As the day progressed the temperature rose to an all-time record of 115°F in Lincoln. The second reason the photo is interesting is that, without air-conditioning, people spent the night sleeping on the lawn of the state capital building in Lincoln. This is a sight not likely ever to be seen again in the United States—at least due to a weather condition. Photographer unknown. Image from the Nebraska State Historical Society.
